Summary: r.proj segfaults after Jul 14 changes
Issue type: module bug
Issue status: None
GRASS version: CVS HEAD
GRASS component: raster
Operating system: MacOS X
Operating system version: 10.4
GRASS CVS checkout date, if applies (YYMMDD):
Initial Comment:
Something happened in the middle of the r.proj.seg->r.proj change that's
causing a segfault on OSX.
GRASS 6.3.cvs (us83-utm16):~ > r.proj loc=world1k map=globe in=globe met=cubic

My build from Jul 14 works for r.proj.seg, but crashes for r.proj. I see in
the CVS history that on Jul 14 some "Message/Debug cleaning" was done to
r.proj, then probably applied to r.proj.seg on Jul 16 as "Synchronize messages
with r.proj", and this seems to agree with the vsfprint crash above.
More recent builds (I have one from Jul 30, as well as today), where r.proj.seg
is now r.proj, also crash.
In main.c of r.proj.seg, if I replace any G_message(NULL) with what it used to
be: G_message(""), it doesn't segfault. And G_done_msg(NULL) -> G_done_msg("").
