Bug description:
dump_syms crashes during the build when creating the breakpad symbols
with gcc 4.7. It isn't recreatable at all on a local build, which is a
bit of a pain.

Unfortunately, valgrind is not much help by default because dump_syms
is statically linked (so memcheck can't hook in to malloc / free).
However, I can do a dynamic build in a PPA and get that build to crash
locally. In this case, I see this in valgrind:
