Description Fangrui Song 2020-04-03 05:14:12 UTC 
sh_entsize(.stab) seems to be wrong since "19990502 sourceware import".

https://sourceware.org/pipermail/binutils/2020-April/110529.html can probably fix it. I noticed that

#define STRDXOFF (0)
#define TYPEOFF (4)
#define OTHEROFF (5)
#define DESCOFF (6)
#define VALOFF (8)
#define STABSIZE (12)

are duplicated in 4 places. A future clean-up can merge them.

    The assembler only supports 32-bit stabs. So set sh_entsize unconditionally to 12.

            * elf.c (assign_section_numbers): Always set .stab sh_entsize to
            12.
