• Merged into: #6

I had the same issue after an svn update.
Try to clean the project (make clean) in /src and do a make clean in /src/wps.
then ./configure and make
After this, no segfault appears.

Perhaps the makefile should be updated?!

make cleanall will clean everything in all subdirectories...let me know if this 
fixes your issue sebastian.

ahh, yes it works now.
should have looked into what 'make clean' really does...

This was the same problem that was reported in issue #6. It was caused by the 
struct pack bug, which was the cause of several issues. Just wanted to make 
sure this wasn't a separate bug, thanks! :)
