From: Kari Pahula <kaol <at> iki.fi> To: 18259 <at> debbugs.gnu.org Subject: bug#18259: 24.3; comint-interrupt-subjob fails to interrupt pthreaded programs Date: Wed, 13 Aug 2014 13:52:30 +0300
Trying to interrupt a debugged program in gud fails. Pressing C-c C-c just displays "C-c C-cQuit" but nothing else happens. This works in Emacs version 23. It seems to me that Emacs 24 doesn't know how to signal stop to programs using pthreads.
