System name: scharoun
Type and version: dec station 3400
Display type: monochrome (i don't know the type)
What were you trying to do?
use Xlib utilities to create cursors from pixmaps.
(see below)
What's wrong:
the routine XCrCursor failed with an unaligned access error.
a dbx stack trace shows five arguments rather than the seven specified
by the various manuals.
What should have happened:
the same code runs on both RT and Vax workstations.
Please describe any relevant documentation references:
none. (but see below.)

exit(0);

ps: this is being send from a vax because send does not work on my
decstation...?
