Sometimes I get crashes (segfaults) on Linux.
So I ran the game in gdb, here's part of the backtrace:
(gdb) bt
#0 0x0823e7d0 in VampWorld::ClipPortal(VampWorld::SSectorPortal const&, View const&, Plane const&, Matrix const&, SRect const&, SRect&) const ()
#1 0x082424b1 in VampWorld::GatherVisibleSectors(View const&, Plane const&, unsigned int, SRect const&, Array<unsigned int>&, unsigned int) const ()
#2 0x08242500 in VampWorld::GatherVisibleSectors(View const&, Plane const&, unsigned int, SRect const&, Array<unsigned int>&, unsigned int) const ()
#3 0x08242500 in VampWorld::GatherVisibleSectors(View const&, Plane const&, unsigned int, SRect const&, Array<unsigned int>&, unsigned int) const ()
It goes on like that forever (>6500 stack frames) - apparently some kind of endless recursion?
