Subject: Re: [PATCH]  solaris 10  isinf and ruby_setenv fixes


Hello,

With this patch it fails similarily. E.g either no memory exception or
segementation fault.
I'm using  sun studio 11 compiler. Here are my configuration flags:

LD="cc -xarch=amd64" LDSHARED="cc -G" DLDFLAGS='-xarch=amd64' CC=cc
CFLAGS="-xO3 -g -mt -fsim
ple=1 -xbuiltin=%all -xlibmil -xlibmopt -xtarget=opteron -xarch=amd64"
CXX=CC CXXFLAGS="-xO3
-mt -fsimple=1 -ftrap=%none -nofstore -xbuiltin=%all -xlibmil -xlibmopt
-xtarget=opteron -xar
ch=amd64 -xregs=no%frameptr" LDFLAGS="-xtarget=opteron -xarch=amd64"
../configure --without-g
cc --with-openssl-dir=/usr/local/openssl-0.9.8
--with-readline-dir=/usr/local

It doesn't matter what is the optimization level.
