--- Comment #4 from Jonathan Wakely ---
The exceptions come from this line:
func = gdb.block_for_pc(int(mgr.cast(gdb.lookup_type('intptr_t'
This casts a function pointer to intptr_t and then tries to find the gdb.Block
corresponding to that address.
The GDB docs say that gdb.block_for_pc will return None, but it seems to throw
instead.
The same thing happens on powerpc64 linux (but not powerpc64le).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68735 --- Comment #5 from Jonathan Wakely --- Ah, I think the problem is that Python 2 has a 42-bit int and so casting a big endian pointer to int loses half the bits.

If the commit above fixed it for libfundts.cc it should fix it for those too. It's possible the problem here is different from the PR 65480 problem for powerpc64 though, so I'll wait to see how your next tests go.
