Carl,
I've expanded examples/tests/addrows.c so it does the sequence you
describe if you hit the button.
I've used memprof to scan for leaks. I've saved the leak info three
times :
- after program startup (memprof.leak1)
- after hitting the button (memprof.leak2)
- after terminating the program with the WM_CLOSE button (memprof.leak3)
The three files are identical :
-rw-rw-r-- 1 danny backx 6202 Dec 4 15:53 memprof.leak1
-rw-rw-r-- 1 danny backx 6202 Dec 4 15:53 memprof.leak2
-rw-rw-r-- 1 danny backx 6202 Dec 4 15:53 memprof.leak3
I'm attaching one for your reference, and the modified addrows.c
to save you the trouble of getting it from CVS.
Based on this, my guess is that the leak is not in XbaeMatrix.
I'm doing this on a PC with Mandrake 10.0 and LessTif 0.94.0 .
