Foo written in C++ also fails with the same message.
Running gdb foo in bash gives the expected result:
gdb stops at first executable line prompting for next gdb command.
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
Failed to resume program execution (ContinueDebugEvent failed, error 87)
These problem seem not longer occur due to upstream changes in gdb 7.12.
I've uploaded a gdb 7.12.1-1 test package.
