I’m still geting same coredumps and .deb package itself is bigger about 20kb. /usr/sbin/nginx is about 800kb when orginal is aprox. 500kb. But still i cant get any more details in coredupms. Could there be other problem? For example packages?
Try commenting out (or removing) any mentions of dh_strip in
debian/rules file.
Best regards,

What does
p *u
and
p *(u->conf)
say (in gdb)?
Why do all pointers on amd64 Linux look like portions of ASCII
strings…
Care to post your config? Are you using any recently added features?
Try turning caching off and see what happens.
Best regards,

Ok, grate! Without dh_strip package weighs 14MB and current coredumps
became readable. Here it is:

Could you please:

ipersia.eu server always produces coredump. -
Post full config for ipersia.eu server.

I have my candidate for this failure. To enable php for many directories
in a domain with different root dirs i use if for php not sugested
location. By the way it’s grate and take me a while to figure 
#php support
if ( $request_filename ~* .php(.*)$ ) { # is it php?
fastcgi_pass 127.0.0.1:9000;
expires off;
}
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
I used if ( $request_filename ~* .php(.*)$ ) { for capability with
apache which inderstands /index.php/someargs as a php file with
/someargs arguments - this is used by SMF option to remove ? from
adress.
Apparently this led to some bogus queries with images extensions that
where passed to fastcgi.
Tu sum up i disabled that option and i’m waiting to see if there are any
results. But it shows that we have to work on the way nginx reads the
real name of the files. Examples of such links you can see on

Using if() on $request_uri/$request_filename suggests that config
should be rewritten, but anyway nginx shouldn’t coredump.
It still doesn’t clear for me what caused such wierd behaviour.
Probably some if’s confused the config parsing code, but the
snipped above isn’t enough to reproduce problem.

By the way, nginx itself doesn’t try to “read the real name of the
files”. It’s up to config author to instruct it what to do.

You still refuse to show it despite being asked at least 3 times,
so there is nothing to talk about.

aparently THIS IS A JPEG… I look through some others coredups and its
always images treated as a php and passed to PHP. Strangely enough this
seams to be killing nginx not php processes.
So i think we’ve nailed the problem, i’ll wait 24h to se if everything
is ok and report here.
But this should rise discussion about recognition of php files by nginx
and $fastcgi_script_name doesnt do the trick. I have to do rewrites for
SMF to make it compatible with apache.
it’s doable but multiple ifs are needed to check if full request name
exists and then pass “file.php/blabla.a44.ext” as a php script:
if ( !-f $request_filename && $request_filename ~* .php(.*)$ ) - that
should work as supposed (apache compatible).

Here you have it. As I said nothing special here.
Using if() on $request_uri/$request_filename suggests that config
should be rewritten, but anyway nginx shouldn’t coredump.
Why? I know that if is in rewrite module in docs but can’t we use it in
other places?
Do you suggest to use nested location rather than if() in that case? But
still (and dont yell) - it worked before.
Posted at Nginx Forum:
Yes, separate normal locations or nested ones is
the way to go.Maxim D.
I read documentation for further details and that’s what i found:
if: “Checks the truth of a condition. If the condition evaluates to
true, then the code indicated in the curly braces is carried out and the
request is processed in accordance with the configuration within the
following block.”
location: “While nested locations are allowed by the configuration file
parser, their use is discouraged and may produce unexpected results.”
Module ngx_http_rewrite_module In examples we can
clearly see that it is used with proxy_pass, which is similar
fastcgi_pass.
I’ll add the break, but as I said try passing JPG files to fastcgi -
this seams to be a problem in my case. Because in some cases
fastcgi_pass was the last if() in location and still it led to the
crash.

Looks like you assume that wiki == documentation. It’s simply not
true.
Yes, nested locations have drawbacks due to some inheritance bugs
(and hence they still aren’t documented in official docs). But
if’s are in fact nested locations under the hood - and they have
the same bugs, plus problems itroduced by the mentioned imperative
nature.
I’m not saying you can’t use if’s. Just warn. It’s up to you to
decide.
I’ll add the break, but as I said try passing JPG files to fastcgi - this seams to be a problem in my case.
This is problem in your config, but not in nginx itself. Feel the
difference. 
I believe checking for “.php(/.)?$" instead of ".php(.)$”
should fix your problem with jpg files (at least if you control
your directory names).
Because in some cases fastcgi_pass was the last if() in location and still it led to the crash.
Could you please provide an example config with fastcgi_pass in
last matched if() that results in nginx crash? Note that only
matched if() matters.
