v0.21.0 fails to compile on raspbian with clang

Seems similar to this issue, so I’m assuming it has something to do with the choice to use clang - https://github.com/android/ndk/issues/506

The same error while compiling master (eb9a1fe03779bf05062b70f14190cb23ff42b46f) on ODROID-HC1 + Armbian 21.02.3 Focal:

Clang bug: https://bugs.llvm.org/show_bug.cgi?id=28629

As a workaround, the --disable-fuzz-binary option could be passed to the configure script.

Also happens on intel 32-bit with sanitizers enabled

MarcoFalke commented at 12:33 pm on May 7, 2021: member

Maybe it can be worked around with a linker flag? https://bugs.llvm.org/show_bug.cgi?id=16404#c12

You can link with builtins by providing –rtlib=compiler-rt.

This line works for me: ./bin/clang a.cc -fsanitize=integer -rtlib=compiler-rt -lgcc_s

Seems to work for me. But it needs more investigation to apply flags in the correct way.

Because #21882 has not been backported to 0.21.

It works fine with clang-8, however.

It seems there are two different bugs.

First one is about __mulodi4 symbol, see the OP, and it should be fixed in #21882.

Second one is about __muloti4 symbol, see #21294 (comment) and #21294 (comment).

The latter looks like an upstream bug:
