 got it in the debugger, another case of NaN sprawl:
(gdb) p gs->frameNum
$1 = 35971
(gdb) bt
#0 0x006332e6 in CGround::GetSlope (this=0x29bb248, x=nan(0x400000),
    y=nan(0x400000)) at rts/Map/Ground.cpp:383
#1 0x006332e6 in CGround::GetSlope (this=0x22eab4, x=5.41808265e-011,
    y=3.20665293e-039) at rts/Map/Ground.cpp:383
Backtrace stopped: frame did not save the PC
(gdb)

I used bibim's debug symbols which don't work too well with backtraces; hopefully, this will be enough.

edit: omg I'm late ;p

 Think I've got it, just need /skip to hurry up.

 Fixed. Somebody with a lot of time should compile Spring with unmasked exceptions and see what turns up, this is getting a bit ridiculous.
