Comment #1 on issue 342 by ramosian.gli...@gmail.com: Segfault in
instrumented programs that use GNU indirect functions.
https://code.google.com/p/address-sanitizer/issues/detail?id=342
For the record, Clang does not support the ifunc attribute yet, so this is
a GCC-only problem.
Am I right that the resolver functions themselves aren't marked anyhow and
may reside in a different TU, so we can't decide to instrument them
differently?
For now you'll need to mark your resolver functions with
__attribute__((no_sanitize_address)). Not sure if something can be done
without messing up with the linker (wonder why the resolver function is
called before .preinit_array initializer).
