Subject: [PATCH] Avoid catching SIGSEGV, defer to system services

The current implementation ignores the basic signal handler requirement
to only call signal safe functions, e.g. backtrace_symbols and
abi::__cxa_demangle. This causes deadlocks when the handler is called
from malloc/free and similar.
