Little Big Adventure using DOS4GW produces a stack overflow #34

I just tried Dune2 with my SoftMPU setup and it works like charm: IBM PS/1 486SX 20Mb RAM SB16 (CT2290) MIDI cable to Joystick port Roland RA-50 MS-DOS 7

SOFTMPU.EXE /SB:220 /IRQ:5 /MPU:330 /RA50

Runs fine, MPU is detected and as I said Dune2 music sounds great.

The I try Little Big Adventure (LBA) after having configured it for MIDI with MPU and FX with SB16 and I get this screen:

Reference: https://es.wikipedia.org/wiki/Little_Big_Adventure (I haven't checked DosBox support for this game, no idea, I always use real retro hardware)

Is this related to issues running SoftMPU in protected mode? Is this a general issue with DOS4GW which is used extensively in multiple games of that time?
