Debugger aborted (core dumped) 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 error message:Failed to resume program execution (ContinueDebugEvent failed, error 87)These problem seem not longer occur due to upstream changes in gdb 7.12.Everything seems fine on x86_64 and with M-x gud-gdb on x86. But when I run M-x gdb on x86 (even with no file), gdb crashes.Thanks for testing.It seems this issue is known [1], so I made a gdb 7.12.1-2 with the work-around from there applied, which seems to fix M-x gdb on x86.
Confirmed. Thanks. Ken -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
