Bug #268: "make benchmark" segfaults on amd64 Linux gcc 4.3.1
http://redmine.ruby-lang.org/issues/show/268

Author: Ed Borasky
Status: Open
Priority: Normal
Assigned to: 
Category: 
Target version: 


OS is Gentoo Linux, 2.6.25 kernel, amd64 architecture
compiler is gcc 4.3.1
cflags were "-g -march=athlon64 -pipe -O3". I haven't tried it with less optimization yet
Ruby was checked out from SVN and is At revision 18054.

make benchmark does this:

ruby 1.8.6 (2008-06-20) [x86_64-linux]	.4.49857091903687
ruby 1.9.0 (2008-07-13 revision 18053) [x86_64-linux]	../benchmark/prepare_so_count_words.rb:9: [BUG] Segmentation fault
ruby 1.8.6 (2008-06-20) [x86_64-linux]

0.935374975204468
make: *** [benchmark] Aborted (core dumped)

I can't tell at this point whether the "ruby" that crashed is the built-in Ruby 1.8 (ruby-1.8.6_p230) or the Ruby 1.9 that's being tested. As soon as I figure out which one it is, I'll post a backtrace from the core dump.
