objtool crash processing drivers/gpu/drm/vmwgfx/vmwgfx_msg.o

I saw this on one randconfig build failing today with yesterday's
next-20250326 (with a couple of patches on top), using gcc-14.2
and the attached config I assume this is a rare configuration:

./tools/objtool/objtool --hacks=jump_label --hacks=noinstr --sls --stackval --static-call --uaccess --module drivers/gpu/drm/vmwgfx/vmwgfx_msg.o
Segmentation fault

I have not tried to analyze it any further, but I would guess that
this is a rare configuration, not a recent regression.
