Hi,
I had a look at this bug and one simple fix you could at least do is
switch the possibly endless loops into an fmod function call. This would
reduce the severity of this bug significantly.

//sometimes, angle==infinite (according to gdb) ??
GetSpeed(norme, angle);
- while(angle < -M_PI) angle += M_PI;
- while(angle > M_PI) angle -= M_PI;
+ angle = fmod(angle, M_PI);
angle *= 180.0 / M_PI;
angle /= 2.0;
And #include <math.h>
By the way, there seem to be similarily unnecessary loops in
src/graphic/sprite.cpp, src/map/ground.cpp, src/map/water.cpp
