Crash also happens immediately on Linux upon trying to enter 3d view.
Here's a stack trace from a debug build:

Seems that this delete here may be the culprit. That array is likely not even yet allocated.
void MapRenderer3D::checkVisibleFlats()
{
// Update flats array
delete[] flats_;
n_flats_ = 0;
for (unsigned a = 0; a < sector_flats_.size(); a++)

Ive tried to find the problem and fix it, but I haven't been able to

That crash info doesn't really help much unfortunately, what map are you opening?

Happens in any map
Sometimes instantly after pressing the toggle 3d button, sometimes I can move the camera in 3d for less than a second before it happens

Hmm that's weird since deleting a null pointer is supposed to do nothing, not crash. Unless the pointer is invalid somehow but I can't see how that would happen.
That being said, I don't like that it's using raw new/delete so will look at changing it to vector and that should hopefully fix it

Tried commit 4921aa9 and it now freezes Slade instead of crashing right away
