i have a rails app that tests fine with “rake spec” but gets a  
segmentation fault when “rake spec:rcov” is run.  
i am on windows xp, ruby 1.8.6, rails 2.1.1, mysql 5

my app is at  
[http://github.com/scottnj/test\_blog/tree/master](http://github.com/scottnj/test_blog/tree/master)  
so maybe someone can try to replicate my error so i know if the  
problem is with my code or something installed on my pc.

here is a copy of my shell output

You could try changing your spec/spec.opts to offer more details  
(instead of default progress maybe spec format).

That will be more simple than for us replicate your exact environment  
(ruby version, gem and such).

i added --spec format to the bottom of my spec.opts so it looks like  
this  
–colour  
–format progress  
–loadby mtime  
–reverse  
–spec format

i’m not sure if this is what you meant. i did a quick search on google  
for some documentation on this file but didn’t find anything.  
anyway, now i am not getting the segmentation fault but “0 examples, 0  
failures” so i think i’m doing something wrong.

spec --help:

Builtin formats for examples:  
progress|p : Text progress  
profile|o : Text progress with profiling of 10 slowest  
examples  
specdoc|s : Example doc as text  
html|h : A nice HTML report

so you need to change --format to: specdoc (and remove the --spec one)

You’re not getting segfault because your code is not being executed :-  
D

Change the spec.opts options again and let us know 🙂

–colour  
–format specdoc  
–loadby mtime  
–reverse

still gives the seg-fault?

This only happens to you while running specs with rcov, correct?

Based on your first message and the last one, it seems the segmentation  
fault is random (not always happens in the same place).

Maybe there is something in rspec or rcov that is affecting the runtime  
stability.

Will try to clone your repo and see what I can find.
