expat: showing 0.0% code coverage even if the static inline function is reached

[catenacyber]

Cf https://introspector.oss-fuzz.com/project-profile?project=expat

This seems to come from
Cf https://storage.googleapis.com/oss-fuzz-coverage/expat/reports/20240113/linux/src/expat/expat/fuzz/xml_parse_fuzzer.c.html#L51

We see that the function's body of ParseOneInput, (likely inlined by the compiler) is shown as covered, but the lines calling it like https://storage.googleapis.com/oss-fuzz-coverage/expat/reports/20240113/linux/src/expat/expat/fuzz/xml_parse_fuzzer.c.html#L71 show a O% coverage, even if they were obviously run as the lines just above and below them...

Would you know about this already ? (bug in clang somehow ? )

I think this may be similar to #482

I think this may be similar to #482

Indeed, any plans to fix it ?
