Put a breakpoint in Fsignal, and when it reports this error, show the backtrace.
When I check the emacs manual, the only reference to Fsignal is:
"To make Lisp errors stop Emacs and return to GDB, put a breakpoint at Fsignal."
Also, there is no reference to Fsignal in the GDB manual.
$ cd /path/to/emacs/src $ gdb ./emacs ... (gdb) break Fsignal (gdb) commands pp errror_symbol
end
(gdb) run Thread 1 hit Breakpoint 3, Fsignal (error_symbol=XIL(0x108b0), data="" at eval.c:1514 1514 signal_or_quit (error_symbol, data, false); void-variable (gdb) continue Keep typing "continue" until error_symbol is invalid_syntax. Then: (gdb) bt OK?
Thank you for the instructions. I'm on it.
