Segmentation fault - Linux 32 bit

[OzFalcon]

Standard Hypseus compiles without any issues. Segmentation fault occurs whenever video tries to display.

./testvldp /home/arcade/zframefile/lair/dl-slates.m2v
Using opengl rendering
Segmentation fault

See attached logs for more information When running with noldp option, Game appears to boot (Boot beeps, Credit sounds)

If you could attach a backtrace (run under gdb), that would be very helpful.

Perhaps I should have been more specific. The trace output needs symbols. Enabling the debug options in Cmake is good, but the build type needs to be Debug also. cmake -DCMAKE_BUILD_TYPE=Debug
