qmatplot compiles normally, then segfaults when the user attempts to add a surface to a 3-d plot. I have tried recompiling with my CFLAGS, CFLAGS="-O1 -pipe", and CFLAGS="-O1 -pipe" LDFLAGS="", all with no change. Reproducible: Always Steps to Reproduce: 1. CFLAGS="-O1 -pipe" LDFLAGS="" emerge qmatplot 2. qmatplot & (as non-root) 3. Graph -> XYZ Axes 4. Graph -> Insert -> Surface 5. (Segfault) Actual Results: Segmentation Fault Expected Results: Add a surface to the plot?

I think this is something the developers of the program have to fix. Looks like they are not too busy maintaining it... http://sourceforge.net/tracker/index.php?func=detail&aid=784616&group_id=76114&atid=546124 If you can find a patch for this problem, please tell us.
