[ruby-core:42001] [ruby-trunk - Bug #5851] make check fails when compiling with GCC 4.7 - *** longjmp causes uninitialized stack frame ***

Issue #5851 has been updated by Vit Ondruch.


Hi Luis,

You can find the GCC glags in the build.log [1]. I was using the following settings: CFLAGS='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4  -m32 -march=i686 -mtune=atom -fasynchronous-unwind-tables'. I will try the flags you are suggesting.

BTW with -O0, it passes (unfortunately fails in other test) and with -O1, I get a bit more verbose output [2]. And this [3] is the backtrace I obtained using GBD.

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.
