Subject: bug#5060: More debugging information
Date: Fri, 27 Nov 2009 23:07:57 -0500 [thread overview]
Message-ID: <874oofl2aq.fsf@maru.md5i.com> (raw)
Shortly before the failure occurs, gdb-frame-handler is called. In the
context of the failure, the frame variable is set to:
((line . "29") (file . "longjmp.c") (func . "__libc_siglongjmp")
(addr . "0xb79ef6c1") (level . "0"))
gdb-selected-file is nil, since there is no 'fullname.
gdb-selected-line gets 29. So, gud-last-frame is '(nil . 29).
gud-display-frame is then called, which calls gud-display-line with the
args from gud-last frame. I.e., (gud-display-frame nil 29). This nil
is what is later causing problems when gud-find-file is called.
My guess is that gud-display-frame should not be called if
gdb-selected-file is nil. But I do not understand the code well enough
to know that this is the case.
