Comment #1 originally posted by bobbens on 2009-04-06T09:07:17.000Z:

Hello,

I can't reproduce at all and valgrind checks come up clean. I've committed a few
patches to try ta address the issue, but in theory it should have been fine already.
Try running a make clean before compiling again and trying the changes.

From what it seems it looks the the "prices" member of Systems structures isn't being
set to NULL as it should, causing all segfaults because it checks against NULL to see
if it should free. It's strange.

Either way, try to sync with trunk again and the make clean and see what happens.
