Description Tomi Kyöstilä 2012-08-08 09:34:26 UTC 
Steps to reproduce:

1. $ gdb
2. (gdb) attach 12688
3. (gdb) continue


Actual results:

Output:
Continuing.
warning: Mach error at "darwin-nat.c:726" in function "darwin_resume_thread": (os/kern) failure (0x5)

The attached process continues to run normally, but gdb does not break on Ctrl-C. When the attached process terminates, gdb returns to the (gdb) prompt.


Expected results:

gdb should break on Ctrl-C.


Running GNU gdb (GDB) 7.5.50.20120806-cvs (configured as "x86_64-apple-darwin10.8.0") on Darwin iMac.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun  7 16:33:36 PDT 2011; root:xnu-1504.15.3~1/RELEASE_I386 i386
Comment 1 Omar Awile 2013-06-25 14:13:43 UTC 
I can confirm this bug. Same behavior with gdb 7.6 on Darwin nyu.local 12.3.0 Darwin Kernel Version 12.3.0 (Mac OSX 10.8.3)
