[GRASS-user] parallel grass operations

[Dmitriy Tyugaev]

Hi list,

When I run my script with parallel grass operations (about 12 processes at
the same time), sometimes I get this error from the g.region module:

*** glibc detected *** g.region: double free or corruption (out):

Tell me please what's the problem?
