OK.  Please justify the patch when posting and in the git log.
"Only 32-bit stabs are supported" would do.

The existing code assumes sh_entsize(.stab)=20 on ELFCLASS64.
However, the assembler only supports 32-bit stabs. So set sh_entsize unconditionally to 12.

	PR gas/25768
	* elf.c (assign_section_numbers): Set .stab sh_entsize to 12.

Hi Fangrui,

Approved - please apply.

> Ping :)

Sorry - I blame the weather - or aliens - or anything but my own laziness.

Cheers

No worries! Nick, can you apply it on my behalf? I don't have a commit bit.
