Description
Dear GMT team,
referring to the entry in the gmt-user forum (where the full script and data are to find)
[[http://gmt.soest.hawaii.edu/boards/1/topics/4103]]
I file a bug issue for grdcontour and the polar projection (-JP). The nasty command line
gmt grdcontour brdf_14/01_brdf.ring.755.00.ps.dat.nc -JP6ir -Xa2c -Ya4c -By30 -Bx30 -Cbrdf_14/01_brdf.ring.755.00.ps.dat.cpt -A- -W+1p -V -K -O >> brdf_14/01_brdf.ring.755.00.ps.dat.ps
crashes on a Intel Mac OSX 10.11.6 (15G31) with GMT 5.2.1 (r15220) (via MacPorts) with
grdcontour: Processing input grid
grdcontour: Allocate memory and read data file

Consistently but more interestingly the almost same behaviour with the same script is obtained on a Linux installation with the combination of
Linux 3.13.0-86-generic #131-Ubuntu x86_64 GNU/Linux
gmt --version 5.1.2 (r14084)
but now the script crashes already with grdimage as
grdimage: Allocates memory and read data file

Luca, the problem is that with this information we are not able to try to reproduce the issue.
We also need the input data (or a small subset that allows to reproduce the problem).
Hello Joaquim, thanks for the reply.
I'm attaching 4 files: the script, the test data, the correct output plot (obtained with -JP6i) and the wrong output plot (with -JP6ir).
This happens for the Intel Mac OSX 10.11.6 (15G31) with GMT 5.2.1 (r15220) (via MacPorts).
The error message reads:
grdcontour: Processing input grid
grdcontour: Allocate memory and read data file
gmt(15967,0x7fff7bf76000) malloc: *** error for object 0x7fae84865a08: incorrect checksum for freed object - object was probably modified after being freed.

./do-gmt-polar.sh: line 39: 15967 Abort trap: 6 gmt grdcontour $NC ${PROJ} $OFF $AXy $AXx $FORMAT -C$COL -A- $CONT -V -K -O >> $PLOT
Hope you can reproduce the behaviour.
Regards.

Correction, yes I can reproduce it. It's that I just run your script and that worked but if I add the 'r' to the projection than it crashes.
Thanks Joaquim.
If it may help, I was experimenting with the development subversion ( 5.3.0_r17114 ) on the Linux box instead, and I get the same error message
grdimage: Allocates memory and read data file
*** Error in `gmt': malloc(): memory corruption: 0x0000000000853770 ***

but now with a different wrong output plot (attached).

- Assignee set to Paul
We had an allocation problem where one test said we needed N points and then the calculation needed 2*N points. Should be fixed in r17145 - let us know. We added a couple of tests to the test suite inspired by your script and they pass.
