Issue with gdb built and linked statically with gcc-6.2

I tried building GDB, version= 7.12.50.20170106, with gcc-6.1 and 6.2 on AIX
7.2 platform. The static linking of GDB with libstdc++ and libgcc library leads
to an issue of broken exception handling. Specifically, running invalid
commands leads to core dump.

Test_result:
