Hello,

I did borrow some assembler files to avoid having to link against
(any) libc. That was for building a DSO, ultimately loaded via glibc.
The effect was that glibc did change the protection of all stacks to
be executable.

Would you consider adding the line [1]
.section        .note.GNU-stack, "", %progbits
to assembly files?

I know this is not a musl bug, and I can easily add the lines myself.

regards, Norbert
