Fix overflow error in breakpad for linux
A computation in the stack unwind algorithm could cause an overflow if a base
pointer read from crashed process is sufficiently close to top of address space.
This causes a memory read that causes the dump thread to crash, resulting in a
failure to generate crash dump. Check fixed to properly detect that this pointer
is greater than actual memory range of current stack.
