[GRASS-dev] d.mon crashes in current 6.3 CVS

GRASS GIS GRASS GIS developer

On 2 32bit and 1 64bit different machines (but all Ubuntu Dapper) d.mon
segfaults for me as follows:

$ d.mon x0
using default visual which is TrueColor
ncolors: 16777216
Segmentation fault
Segmentation fault
Problem selecting x0. Will try once more
Segmentation fault

Monitor pops up for a short while and dissapears.

I can't get obtain a backtrace. Gdb only says: "Program exited with
code 01."

Can anybody reproduce?

Yes:
