Description Pekka Savola 1999-09-26 08:17:13 UTC
joe-2.8-22

Joe seems seems to segfault when exiting (Save+exit or
just exit) from editing/viewing a really big file.  I tested
several files, and it seems the limit for safe use is 4
megabytes (or something between 100,000 and 110,000 lines).

The problem is vclose() uses vsrm() to free vfile->name allocated from mktmp(),
vclose() should use free() to free it.
here is a patch:
