Could you send the output of

        readelf --program-headers ./main

where main is TinyCC generated, segfaulting executable?

And could you try linking your program with musl statically? Maybe
something like

        tcc main.c -o main -static

Recent TinyCC may generate ELF binaries with a zero-lengthed LOAD
segment, which musl's dynamic linker doesn't handle correctly. I thought
it's a musl problem and a patch has been sent to musl upstream[1].
