Ruby 1.9.1 HEAD compiled with gcc-4.4.x -O2 causes Segmentation fault.
I can not reproduce on amd64.
How to reproduce:
svn co -r 26571 http://svn.ruby-lang.org/repos/ruby/branches/ruby_1_9_1
cd ruby_1_9_1
autoconf
./configure
make miniruby
./miniruby -e 'catch(:foo){throw :foo}'
Ruby does not abort when use `./configure optflags=-O0`,
`./configure optflags=-O1`, or `./configure optflags=-O3`.
Then it seems gcc optimization bug.
- please recheck with gcc-snapshot-20100414 (GCC-4.5.0), when it is built.
- please try to combine/bisect object files built with -O0/-O2 to
identify the maybe miscompiled file.
then split the file to identify a miscompiled function ...
