Summary: smbd segfaults on arm architecture
Description:
Using a buildroot compiled uclibc toolchain and version 0.9.29 of uclibc a
samba smbd (actually all samba binaries) segfaults immediately after
starting.
The toolchain has been compiled using linuxthreads.old/stable. Other
programs compiled with the toolchain work, e.g. busybox.
a gdb session shows the following output:
bash-3.2# gdb smbd
