grdtrack -E multiple lines crashes
|Target version:||Candidate for next bugfix release|
|Affected version:||5.1.1||Platform:||Mac OS X|
Attempting to enter multiple lines to the -E argument of grdtrack results in an error.
This command runs fine:
gmt grdtrack -GESP_032711_1955.lowpass.grd -E184.3181/15.2303+l0.5k+o45+d > track.txt
Both of the following commands crash. Note that the first command is what I want to be able to do; to have the same center point and have radial lines at different angles from that point. I tested the second command also since the documentation seems to possibly indicate all the flags being at the end, although that would not allow me to do the lines I want, since I want different angles from the same point.
gmt grdtrack -GESP_032711_1955.lowpass.grd -E184.3181/15.2303+l0.5k+o45+d,184.3181/15.2303+l0.01k+o90+d > track.txt
gmt grdtrack -GESP_032711_1955.lowpass.grd -E184.3181/15.2303,184.3181/15.231+l0.01k+o90+d > track.txt
Both commands crash with the identical error:
grdtrack: Syntax error -Q: Valid coordinate codes are [lcr][bmt] and z[+-]

Thanks for your consideration of this error.

The problem was that a local variable (pos2) was not reset to 0 before each new line (only the first one), and this lead us astray and into the bad message. Should be fixed in r13119, let me know. Note only one +d is needed as it is a global modifier.
