This behavior could be caused by a couple of  issues. Can you check if '
dl_unwind_find_exid' does return something meaningful in
'os/src/lib/ldso/arm/platform.c'?  This function is used by the
libgcc_eh code in the dynamic case only. Second, can you send me the
output of 'objdump -R bin/libc.lib.so' and the same for 'bin/test-libc'.
There could be some unsupported relocation types. What EABI version is
this platform using?
