The problem is that rs6000_frame_cache attempts to read the stack backchain via read_memory_unsigned_integer, which throws an exception if the stack pointer is invalid. With this patch, it calls safe_read_memory_integer instead, which doesn't throw an exception and allows for safe handling of that situation. gdb/ChangeLog 2014-09-12 Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com> Ulrich Weigand <uweigand@de.ibm.com> PR tdep/17379 * rs6000-tdep.c (rs6000_frame_cache): Use safe_read_memory_integer instead of read_memory_unsigned_integer. gdb/testcase/ChangeLog 2014-09-12 Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com> PR tdep/17379 * gdb.arch/powerpc-stackless.S: New file. * gdb.arch/powerpc-stackless.exp: New file.
