Maybe not be relevant for answering your question, but the issue doesn't seem to be restricted to AIX. It occurs on Windows with mingw as well, see gdb/21078 ("gdb compiled with mingw32 crashes on Windows7 when entering any invalid command"). In addition to those PRs, It'd be great to get some of the DWARF piece handling fixes in GDB 8.0, particularly the fix for gdb/21226. There's a patch set available that "just" needs review: https://sourceware.org/ml/gdb-patches/2017-04/msg00177.html Also, I wonder who can look at exp/21162 ("GDB internal error with unbounded array typecast expression"). It's a regression introduced when adding variable length array support in April 2014. The author, Sanimir Agovic, doesn't seem to be active in GDB development any more? The patch was reviewed by Joel Brobecker, though... ;-) And last week a GDB internal error in value.c was reported as gdb/21356. I haven't checked whether that is a regression or not. -- Andreas
