[GRASS-dev] Parser problem in GRASS 7

[Markus Neteler]

Hi,

by chance I came across a strange problem:

# wrong param name "inbut":
GRASS 7.0.svn (spearfish60):~ > r.colors inbut=diff col=differences
Aborted

Any wrong name currently leads to "Abort" rather than the expected error
message from the parser. They are generated, then get lost.

Here the backtrace:

The problem happens somewhere in parser.c, line 1373.
