It's the GDB 7.7's demangler that crashes on certain symbols
created by GCC from some C++11 code, see e.g.
https://sourceware.org/bugzilla/show_bug.cgi?id=16957
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61233
and others. The crash is already triggered when a binary
containing certain symbols is loaded, already without any
attempt to run something.

GDB 7.6 is a more robust choice in this respect, but this
version suffers from some performance issues (see e.g.
https://sourceware.org/bugzilla/show_bug.cgi?id=15412), but
is a better choice in this case.

I can't say anything aboout 7.8 yet.
