I'm seeing P9P acme (running in linux on a Wintel PC) crash
intermittently when executing "New xxx", and if that doesn't cause a
crash middle clicking Del in the tag of the newly created xxx window
nearly always causes a crash. I just downloaded and installed the
latest plan9port.tgz to make sure I'm current and I still see the
problem
The couple times I saw the crash when executing New, the following
message was written to stdout or stderr:
devdraw: reading wsys msg: Connection reset by peer
In the cases where New xxx doesn't cause acme to crash, it creates a
+Errors window containing the line
can't open xxx: No such file or directory
as well as creating the window for the file xxx.
If I then try to Del the xxx window, acme crashes after writing the
following message to stdout or stderr:
acme: can't find text in filedeltext: No such file or directory
or
acme: can't find text in filedeltext: Success
Several times when it crashed Del-ing the window I got a message like:
*** glibc detected *** corrupted double-linked list: 0x080e8328 ***
I haven't figured out how to debug P9P programs using either acid or gdb
(breakpoints don't seem to work), so I haven't had any luck tracking
this down.
Has anyone else noticed these problems? Have any ideas what is going wrong?
thanks,
vbnut

Found using libefence, and fixed. Thanks for the detailed recipe
for making it crash. I saw this once about six months ago,
but I couldn't reproduce it.
