Subject: Re: Emacs seems awfully unstable on OS X lately
Date: Sun, 16 Sep 2012 02:47:32 +0200 (CEST) [thread overview]
Message-ID: <20120916.024732.2273988454371877554.hanche@math.ntnu.no> (raw)
In-Reply-To: <20120915.115711.33388204433633302.hanche@math.ntnu.no>
Well, after a day of testing I am inclined to blame revision 109972
for the instability on OS X. At least, I get crashes with that
revision and later ones, and so far I haven't seen any crashes with
earlier revisions. I am running on revision 109971 now. I'll probably
have to use it for several hours before I can feel confident in this
conclusion, however.
Now I know nothing about Objective C, but the added code in nsterm.m
doesn't look to me like something that would cause crashes.
However that may be, I managed to provoke a crash with gdb attached,
but didn't get a useful backtrace; only this:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000011
0x00007fff8fc7ae90 in objc_msgSend ()
(gdb) back
#0 0x00007fff8fc7ae90 in objc_msgSend ()
#1 0x0000000000000000 in ?? ()
The backtrace supplied by the OS X crash reporter is a lot more
informative, I suppose. I supply it below.
