i'm trying to get fastcgi to work on solaris. my rails application works
fine with normal cgi, but with fastcgi i always get a segmentationfault.
the app runs normally with fastcgi under linux but that doesnt really
help :)

tested systems:
uname -a
SunOS ... 5.10 Generic_118833-17 sun4v sparc SUNW,Sun-Fire-T200
SunOS ... 5.10 Generic sun4u sparc SUNW,Sun-Blade-100
SunOS ... 5.10 Generic sun4u sparc SUNW,Sun-Fire-280R

i've tried several rubyversions with the same error (1.8.x), some
selfcompiled with sun-compiler or gcc, some precompiled (blastwave).
as httpserver i aim for apache 1.3 (included in oracle applicationserver
with mod_fastcgi), but tried apache 2.2 as well (with mod_fcgid,
i followed several instructions on the net, eg
i've also tried a simple test-application to rule out a problem in the
rails application.

the actual errormessage looks like this:
/usr/local/lib/ruby/1.8/timeout.rb:52: [BUG] Segmentation fault
ruby 1.8.5 (2007-03-13) [sparc-solaris2.10]

[Mon Mar 19 08:41:58 2007] [error] [client] [ecid:
1174290116:,0] FastCGI: incomplete headers (0 by
tes) received from server "<rails-app>/public/dispatch.fcgi"
[Mon Mar 19 08:41:58 2007] [warn] FastCGI: (dynamic) server
"<rails-app>/public/dispatch.fcgi" (pid 22852) terminated due
 to uncaught signal '6' (Abort), a core file may have been generated

the line in timeout.rb is Thread.start.
at some times (other versions of ruby, gems etc...) i've got a
segmentationfault in another rubyclass, also at a line with Thread.start

what else should i try? or does it look like a bug in ruby? i don't
really have the know-how to debug the coredump but if you think it to be
rewarding, maybe i should consider trying...
