Summary: Mach error in function darwin_resume_thread when
continuing after attaching to a process
Product: gdb

Status: NEW
Severity: normal
Priority: P2
Component: gdb
AssignedTo: ***@sourceware.org
ReportedBy: ***@gmail.com

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":

The attached process continues to run normally, but gdb does not break on

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)
