#1705: i.group segfaults on empty input
---------------------+------------------------------------------------------
Reporter: neteler | Owner: grass-dev@…
Type: defect | Status: new
Priority: minor | Milestone: 7.0.0
Component: Imagery | Version: svn-trunk
Keywords: i.group | Platform: Linux
Cpu: x86-64 |
---------------------+------------------------------------------------------
When running i.group with *empty* input (as it can happen
from an unsuccessful g.mlist call piped into it), it segfaults:
{{{
i.group group=tmean_avg input=""
Segmentation fault (core dumped)
}}}
The real call was:
{{{
i.group group=tmean_avg input=`g.mlist rast pat="tmean.1981_2010.??.avg
sep=,"`
Segmentation fault (core dumped)
}}}
but g.mlist did not return anything due to a typo in
the map name pattern.
GDB (line broken for readability):
{{{
(gdb) run group=tmean_0_25deg_1981_2010_avg \
input=`g.mlist rast pat="tmean_0_25deg.1981_2010.??.avg sep=,"`
Program received signal SIGSEGV, Segmentation fault.
