Hi!
I'm in the process of updating m4 in pkgsrc, and found an old patch.
The problem is that a sparc v9 specific flag is enabled on sparc v8,
leading to core dumps.
I don't own such hardware, but a detailed debugging session has been
tracked in https://gnats.netbsd.org/56498
I'll attach the patch.
Cheers,
Thomas
