Re: grdmath problems

Hi Branden,

(only if you aren't tired of this)

* compile GMT 4.5.11 without any optimization and with debug flag.
   This is done setting CFLAGS environment variable, in bash shell:

   export CFLAGS="-g -O0"

   Then go to gmt-45-11 directory and ./configure and make (no install)

* Install valgrind in Ubuntu. Valgrind is a tool for debugging programs.
   Then with GMT freshly compiled, go to gmt-4-5-11/src directory and run
   your commands:

./grdmath -R0/10/0/10 -I1 X = 1.grd

./grdmath -R0/10/0/10 -I1 X = 2.grd

valgrind ./grdmath 1.grd DUP DUP 10 LE 0.65 MUL EXCH DUP DUP DUP 10 GT  
EXCH 20 LE MUL EXCH 10 SUB 10 DIV -0.05 MUL 0.65 ADD MUL EXCH DUP DUP  
DUP 20 GT EXCH 30 LE MUL EXCH 20 SUB 10 DIV -0.07 MUL 0.60 ADD MUL  
EXCH DUP DUP DUP 30 GT EXCH 40 LE MUL EXCH 30 SUB 10 DIV -0.08 MUL  
0.53 ADD MUL EXCH 40 GT 0.45 MUL ADD ADD ADD ADD 686 2.grd DIV EXCH  
POW MUL = 3.grd

Look that you're running under valgrind the grdmath in the src directory!

Paste and send the screen output
