             Bug #: 14443
           Summary: Mach error in function darwin_resume_thread when
                    continuing after attaching to a process
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: tomi.kyostila@gmail.com
    Classification: Unclassified


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.
