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].
