Maybe you will be able to see where does > this SIGTRAP originate from. (gdb) handle SIGTRAP stop print pass SIGTRAP is used by the debugger. Are you sure you want to change it? (y or n) y Signal Stop Print Pass to program Description SIGTRAP Yes Yes Yes Trace/breakpoint trap (gdb) run Starting program: /home/larsi/src/emacs/mystery/src/emacs Program terminated with signal SIGTRAP, Trace/breakpoint trap. The program no longer exists. This is with a fresh checkout. I'm starting to think there's a bug in the version of gdb on Debian/bookworm that the current trunk is somehow hitting. Perhaps I should just try to bisect the current trunk -- this started happening this past week. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
