M4: Orion Burger: Crash on strict-alignment architectures

Description
Today's Git HEAD immediately crashes with a SIGBUS on the old mips64el device I have here (little-endian, 64 bits, strict alignment). The game is the French release of Orion Burger from my original CD -- I guess the same issue appears with the demo.
Building with --enable-ubsan on a regular x86-64 computer is a more accessible way of reproducing the issue.
I'm attaching both the GDB backtrace from the MIPS device, and the UBsan logs.
