Re: Long Error Message

[Marty Kraimer <mrk@aps.anl.gov>]

errlog allows a maximum message size of 256 characters.
It allows an extra 256 characters in an internal buffer.
Until extra is > 256 there is no buffer overflow.

Thus the following error message does not actually cause a problem.


In 3.14 errlog has been modified so that a buffer overflow can not occur.
