Subject: [PATCH] Fix a Breakpad crash during teardown when
USE_PROTECTED_ALLOCATIONS is in effect.
BUG=none
TEST=Apple Crash Reporter logs from processes in which Breakpad handles the
crash should point the finger at the actual crash source, not the
Breakpad thread's attempt to write to unwritable memory.
