Issue #5851 has been updated by Luis Lavena.


Can you provide a simple example that reproduces this?

Have you tried compiling with debug symbols and go over GDB?

Can you provide information of the resulting GCC flags of configure that were used to generate the libruby.so and ruby executable?

Have you tried -fno-omit-frame-pointer?

I am experiencing strange test error [1] when compiling Ruby 1.9.3-p0/1.9.3-p19/2.0.0 rev 34217 with GCC 4.7 in Fedora Rawhide [2]. Everything worked just fine with GCC 4.6.
