    I have a bug in my X application that seems to appear randomly when I
run my application on a Sun 3/60 and appears not-so-randomly on a Sun 4/110.
The error is a segmentation violation.  When I debug with dbx it says it
blows up in XrmStringToQuark.  The error occurs when creating certain widgets
on the Sun4 and occasionally occurs upon destroying a widget on the Sun3.

Below is a small dbx session involving the error.  Could somebody tell me
what XrmStringToQuark is supposed to do.  If somebody recognizes this error
or thinks they may know what the problem is please let me know.


dbx session:

        I hope that I did something obviously stupid so that someone will
recognize it and I can get past this bug in my program.  Send any help or
advice to:
