Bug#577973: gcc-4.4: optimization bug on x86



Package: gcc-4.4
Version: 4.4.3-7
Severity: normal

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.
