- Organization: ExactCode
Hi all,
this is just a tiny note, that gcc-4.0 does produce miscompiled binaries
on sparc(32)-linux with -mcpu=ultrasparc. Some binaries work, however
many such as bash, curl or gzip segfault.
I know this is not a reduced testcase, just a note. I try to invest some
time over the weekend to debug this and hopefully produce a reduced
testcase. So far this only happens with v9 or above optmiizations. v8
optimized binaries pass checking.
Yours,
