Which gcc? (gcc --version)

I am using gentoo (but 32bit) for upstream testing,
it should fail here too then:)

But that code is there since 1.1.0, so I guess something in gcc/glibc
changed probably and uncovers some old bug.

try "ulimit -c unlimited" and then run that command

you can also define where core files will be stored using
sysctl kernel.core_pattern=/<some dir>/core
