Subject: [PATCH] fix(callstack): guard against NULL from strchr in symbol
 parsing

backtrace_symbols lines without a '+' (stripped/static frames) make
strchr return NULL; the code then dereferenced it via if(*plus),
crashing while dumping callstacks on the POSIX/macOS path. Check the
pointer before dereferencing.
