Bug in egcs 1.1.2
JA
compiler included into the egcs1.1.2 package
there is a bug in file operations. The users,
including me, of the Monte Carlo program MCNP
complain about that. The extracted pure form
of this bug can be examined with a short
program written by Jeff Siebers.
g77 up to 0.5.23 seem to be free of this bug.
Is any chance that a work around and/or a correction
can be implemented?
This bug has been reported to EGCS people with no
response.

They have been pretty responsive for me.
You need to use the latest version, though. That is gcc-2.95.2,
IIRC. Or probably that + the latest snapshot as well.
If these still show the bug and you can cut the code down to a
reasonable piece of code, I am sure you will get a response soon.
Wether they can fix it out of the box is something different :-)

Jochen,
Forgot to mention that this bug is still in egcs-2.95 as of
19990628 pre-release. According to Skip Egdorf <h...@lanl.gov>
the use of endfile destroys the readability of the file.
Up to gcc-27.2.3 and g77-0.5.21 (perhaps even up to g77-0.5.23)
everything was OK.

Jeff had indeed submitted a bug report, and Toon (g77 guru and a regular
here) has submitted a fix for this bug, and will show in the next release.
You can of course rebuild your current release with his patch and hope for
the best. See:

It's correct that I submitted the fix, but - to be brutally honest - David M.
Gay wrote it :-)
