(gdb) where
#0  0x8000faac in ?? ()
#1  0x8000facc in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)

Not sure if this is a gdb problem, though - never even tried to debug klibc.
With the mentioned patch klibc compiles, but all utils just segfault,
strace is as short as seen above.

without this patch it doesn't compile at all:
