[GRASS-dev] g.copy rast=

[Patton, Eric]

Martin,

I can confirm a segfault on using g.copy, with today's CVS on Ubuntu 6.06. 

g.copy exits with a segfault, but the maps seems to get copied to the destination mapset as requested anyway. Only the command line run reaches a segfault, not the GUI version. Or maybe the error just isn't visible from the GUI.

Output from gdb:

Devs, any other info needed to diagnose this error?
