Hi,

in static-pie, relocations get processed in _start, before main() is
called. In musl, this is done by linking with rcrt1.o as start file
instead of crt1.o. And that file processes all relative relocations. You
can check with readelf -r what the relocation types are. If they are not
relative, they will not be processed.

What you are seeing seems indicative of missing relocation processing.
Is it possible you are linking in the wrong start file? gcc -v should
output the command line it feeds to the linker.

Ciao,
Markus
