SIGSEGV in alloc.c
For info on my installation or system see attached files. I have been
getting segfaults in the past few xemacs. Well I sat down and stepped
through the source code until I found where it is happening. Here is the
gdb output. I am not a programmer so I am not even going to try to figure
this out. I see from the list that there may be others with this problem.
