2:05 a.m.
I used macports to install xemacs on my Mac Pro. I've appended hardware and software
information about the computer, as well as the installation info below.
I get a segmentation fault when I try to open a file called ProcessImage.py. If I copy
ProcessImage.py to a new file named "foo", the file opens without a problem. If
I copy ProcessImage.py to a new file named "foo.py", I get a segmentation error.
If I copy ProcessImage.py to a new file named "foo.cc", I get a segmentation
error. The segmentation error I get when I run xemacs ProcessImage.py is given below.
I'm guessing the problem is something to do with the fontification of the programming
languages.
I've looked hard for a core file but have had no luck. "ls -a ~" does not
show any file with core in its name, and doing "ls-a ~ | grep core" returns
nothing. Similarly, there is no file with "core" in its name in the directory
from which xemacs was executed.
ls -a /cores returns nothing.
find /opt -name "core" -print | grep xemacs returns nothing.
find /opt -name "core.*" -print | grep xemacs returns nothing.
find /opt -name "core.*" -print returns a variety of file names related to
python (they either have .py, .pyc, in their names or are in a python directory)
find /opt -name "core.*" -print | grep -v py returns nothing
If you can suggest another place to search for a core file, please let me know.
I have also done a fairly extensive search for a file called PROBLEMS in the /opt
directory, including using the commands:
find /opt -name "*PROBLEMS*" -print
find /opt -name "*Problems*" -print
find /opt -name "*problems*" -print
The first two commands returned nothing, and the last returned the file:
/opt/local/lib/xemacs-21.4.22/xemacs-packages/man/auctex/preview-problems.texi, but I
didn't see anything relevant in that file.
Here is the xemacs output:
Fatal error (11).
Your files have been auto-saved.
Use `M-x recover-session' to recover them.
Your version of XEmacs was distributed with a PROBLEMS file that may describe
your crash, and with luck a workaround. Please check it first, but do report
the crash anyway. Please report this bug by invoking M-x report-emacs-bug,
or by selecting `Send Bug Report' from the Help menu. If necessary, send
ordinary email to `xemacs-beta(a)xemacs.org'. *MAKE SURE* to include the XEmacs
configuration from M-x describe-installation, or equivalently the file
Installation in the top of the build tree.
*Please* try *hard* to obtain a C stack backtrace; without it, we are unlikely
to be able to analyze the problem. Locate the core file produced as a result
of this crash (often called `core' or `core.<process-id>', and located in
the directory in which you started XEmacs or your home directory), and type
gdb /opt/local/bin/xemacs core
then type `where' at the debugger prompt. No GDB on your system? You may
have DBX, or XDB, or SDB. (Ask your system administrator if you need help.)
If no core file was produced, enable them (often with `ulimit -c unlimited'
in case of future recurrance of the crash.
