## Message

```
fix: the Linux crash log names the functions a signal stopped in

glibc's backtrace_symbols_fd reads only dynamic symbols, so a SIGSEGV's frames
showed bare offsets. The handler now starts the executable again with
--symbolize, which reads the frames' functions from its own symbol table; the
crashed process makes only async-signal-safe calls, and the raw frames still
come first.
