There was already a glibc bug reporting this. I've done the required changes to
reopen it.

I've proposed a RFC patch on the libc-alpha mailing list which fixes the issue:
https://sourceware.org/pipermail/libc-alpha/2021-August/130129.html
It does have a few downsides: it turns all i18n

The proposed fix "gcc9-pr90193.patch" applied on top of gcc-8.3.0 fixes the
issue for both x86-64 and for x86-32 (-m32) from a 64-bit x86 gcc.

By the way, it can also be reproduced by replacing the "jmp" instruction within
the inline asm by a ".long":
# 1 "test-asm-goto-data.c"
# 1 ""
# 1 ""
# 31 ""
# 1 "/usr/include/stdc-predef.h" 1 3 4
# 32
