I see a timeout in gdb.base/random-signal.exp, Continuing.^M PASS: gdb.base/random-signal.exp: continue ^CPython Exception <type 'exceptions.KeyboardInterrupt'> <type exceptions.KeyboardInterrupt'>: ^M FAIL: gdb.base/random-signal.exp: stop with control-c (timeout) it can be reproduced by running random-signal.exp with native-gdbserver in a loop, like this, and the fail will be shown in about 20 runs, $ (set -e; while true; do make check RUNTESTFLAGS="--target_board=native-gdbserver random-signal.exp"; done) In the test, the program is being single-stepped for software watchpoint, and in each internal stop, python unwinder sniffer is used, #0 pyuw_sniffer (self=<optimised out>, this_frame=<optimised out>, cache_ptr=0xd554f8) at /home/yao/SourceCode/gnu/gdb/git/gdb/python/py-unwind.c:608 #1 0x00000000006a10ae in frame_unwind_try_unwinder (this_frame=this_frame@entry=0xd554e0, this_cache=this_cache@entry=0xd554f8, unwinder=0xecd540) at /home/yao/SourceCode/gnu/gdb/git/gdb/frame-unwind.c:107 #2 0x00000000006a143f in frame_unwind_find_by_frame (this_frame=this_frame@entry=0xd554e0, this_cache=this_cache@entry=0xd554f8) at /home/yao/SourceCode/gnu/gdb/git/gdb/frame-unwind.c:163 #3 0x000000000069dc6b in compute_frame_id (fi=0xd554e0) at /home/yao/SourceCode/gnu/gdb/git/gdb/frame.c:454 #4 get_prev_frame_if_no_cycle (this_frame=this_frame@entry=0xd55410) at /home/yao/SourceCode/gnu/gdb/git/gdb/frame.c:1781 #5 0x000000000069fdb9 in get_prev_frame_always_1 (this_frame=0xd55410) at /home/yao/SourceCode/gnu/gdb/git/gdb/frame.c:1955 #6 get_prev_frame_always (this_frame=this_frame@entry=0xd55410) at /home/yao/SourceCode/gnu/gdb/git/gdb/frame.c:1971 #7 0x00000000006a04b1 in get_prev_frame (this_frame=this_frame@entry=0xd55410) at /home/yao/SourceCode/gnu/gdb/git/gdb/frame.c:2213 when GDB goes to python extension, or other language extension, the SIGINT handler is changed, and is restored when GDB leaves extension language. GDB only stays in extension language for a very short period in this case, but if ctrl-c is pressed at that moment, python extension will handle the SIGINT, and exceptions.KeyboardInterrupt is shown. Language extension is used in GDB side rather than inferior side, so GDB should only change SIGINT handler for extension language when the terminal is ours (not inferior's). This is what this patch does. With this patch applied, I run random-signal.exp in a loop for 18 hours, and no fail is shown. gdb: 2016-01-08 Yao Qi <yao.qi@linaro.org> * extension.c: Include target.h.
