I pushed a patch (a few hours after you opened this bug) that completely
rewrites the way GDB deals with corefile generation. Take a look at Bug 16092.
Now GDB does not blindly skips readonly segments; it respects the value of
/proc/PID/coredump_filter which can be modified to make it dump segments that
were not being dumped before. I think this can help in this situation.
