#506: v.out.ascii segfault when exporting columns from the attribute table
-------------------------+--------------------------------------------------
Reporter: dylan | Owner: grass-dev@lists.osgeo.org

Priority: major | Milestone: 6.5.0

Keywords: v.out.ascii | Platform: Unspecified

-------------------------+--------------------------------------------------
v.out.ascii is giving a segfault when a column is supplied to the
'columns' argument. Example with the spearfish database:

{{{
v.out.ascii in=bugsites format=point columns=str1

[...]

D4/5: eval_node node_type = 2
D4/5: right = 2
D4/5: right_dval = 1.000000
D4/5: operator = 11
D4/5: condition = 0
D2/5: load_table_head(): tab = 2,
/home/dylan/grass/spearfish60/PERMANENT/dbf//bugsites.dbf
Segmentation fault
}}}

I have tried this with several vector files using the DBF backend, all
with the same result. Using the MySQL backend v.out.ascii appears to work
fine.

Comment (by hamish):

works for me.

{{{

}}}

I don't think it makes a difference, but //bugsites.dbf ?

Yeah that did look kind strange... is that something I can fix with
db.connect?

Cheers,

Comment:

Updates: with a recent SVN update, I see that v.out.ascii columns=...
works as expected, except when the column name may be an SQL reserved
word.

This does not work:
{{{
v.out.ascii pits columns=Comment
}}}

This works:
{{{
v.out.ascii pits columns=Max_PDOP
}}}

I wonder if there is something that can be done about this...
