GMT

Hi GMT Team,

I am getting segfaults when there are blank lines present in a "here" document such as the this example:

gmt psxy -P -X4 -R0/20/2017-04-01T/2018-01-31T -JX20/-35 -BWeSN -V -S <<END > test.ps 
#--- Weekends
> -G200
10 2017-03-18 20 bb2017-03-20
> -G200
10 2017-03-25 20 bb2017-03-27
> -G200
10 2017-04-01 20 bb2017-04-03
> -G200
10 2017-04-08 20 bb2017-04-10

END

and when input files (same content as the "here" redirect above, but in separate file) are used. This is the error report:

psxy: Processing input table data

This version without additional spaces between the last data and the END statement works fine (both in "here" documents as well as separate input files):

gmt psxy -P -X4 -R0/20/2017-04-01T/2018-01-31T -JX20/-35 -BWeSN -V -S <<END > test.ps 
#--- Weekends

> -G200
10 2017-04-08 20 bb2017-04-10
END

I'm not sure whether this is intended behaviour? I would have expected that GMT/psxy simply ignores additional blank lines at the end of a file or input.

Mac OS 10.9.5 GMT r17714 (svn).
