Sometimes instead of getting segmentation fault I get this exception:

Does raising your stack limit help?

Thanks

I raised the stack limit from 8192 to 32768, but without any luck.

That's a known problem. Apparently, there is some buggy code in ruby
1.9.1 that triggers different code generation in recent GCC, causing
this segfault. In Debian, we "solved" it by upgrading to ruby 1.9.2.

If you use 1.9.1, you may work around the problem by -O3.

$ ./configure optflags=-O3
