Wine backtrace

Eve Online frequently crashes with a page fault error, which seems to happen
randomly _but only_ when the game is loading in-game structures/geometry (when
undocking from a station or when loading space after a gate jump).

EVEs rendering engine appears to be using dynamic page allocation so no idea
how to debug this.
The full wine backtrace is attached.

The culprit seems to be the load float instruction which seems to load a 8-byte
array (fld [edx+eax*8] - eax being the offset, and probably corrupting for some
reason), as confirmed by the backtrace:

fldl    0x0(%edx,%eax,8)

I have tried debugging the graphics engine to find where this instruction is
located but to no avail - maybe JIT?

The game does not produce any errors itself and just freezes, the wine debugger
window opens shortly after that.

Tested with:
All major Wine versions between 3.0 and 3.16.
