I can confirm that this happens also with gdb-7.11.1-1 but not 
gdb-7.10.1-1.  (I tested on x86_64, since gdb-7.10.1-1 is broken on x86.)

It also fails with M-x gdb instead of M-x gud-gdb, but with a different 
error message:

   Failed to resume program execution (ContinueDebugEvent failed, error 87)
