Subject: [ruby-core:20425] stack consistency error with gcc 4.3.1 and -O2

hi,

when compiling 1.9.1 preview2 with
gcc (SUSE Linux) 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision 135036],
it dies with a stack consistency error. compiling it with -O0 make the build pass.

[[[
./miniruby -I./lib -I.ext/common -I./- -r./ext/purelib.rb ./enc/make_encmake.rb --builtin-encs="ascii.o us_ascii.o unicode.o utf_8.o" --builtin-transes="newline.o" enc.mk 
/usr/src/packages/BUILD/ruby-1.9.1-preview2/rbconfig.rb:174: [BUG] Stack consistency error (sp: 66, bp: 64)
ruby 1.9.1 (2008-12-01 revision 20438) [i586-linux]
