teTeX version: 1.0.6
When using Omega, if an error occurs, typing ``e'' at the error
prompt is supposed to start an editor, open the file being TeXed,
and go to the line at which the problem was detected. Instead,
Omega apparently starts an editor without specifying a file -- vi
opens a new (empty) file in /tmp with a weird temporary name;
emacsclient causes an open Emacs to flash or starts Emacs; Emacs
starts with an empty document.
I discovered this problem when I was going over the failed build
log for tetex-bin from the Debian PowerPC build daemon. The
compiler reported the following warning:
omega3.c: In function `closefilesandterminate':
omega3.c:253: warning: passing arg 1 of `calledit' from
incompatible pointer type
After investigation, the problem turned out to be caused by the
type of calledit's first argument, which was defined as an
ASCIIcode * when it was really being passed a packedASCIIcode *.
Both types are usually unsigned char *s, but in Omega, ASCIIcode
is defined to be an unsigned short. The following patch to
texk/web2c/web2c/coerce.h and texk/web2c/lib/texmfmp.c fixes the
problem.

You might want to change my hack to provide a packedASCIIcode *
for MP (in coerce.h) by declaring it somewhere else.
