OK, your glibc looks pretty standard with no newer extensions like tls=20=

support.

What does ldd a.out show? If it is linked against libpthread, it will=20
segfault since r2 is reserved by the ABI as a thread pointer. glibc=20
implementation honours that, unlike our sheepthreads.

A simple "gcc paranoia.cpp" should not cause a dependency on=20
libpthread. If it happens, please send me the output of "gcc -v" to=20
know how Debian people configured it.

Can you also try "gcc -ffixed-r2 paranoia.cpp" ?

Thanks,
