--- Comment #4 from Christian Holler (:decoder) <chol...@mozilla.com> ---
I can perfectly reproduce this on Clang 5 with the testcase from the original
comment on x86:

$ clang-5.0 -fsanitize=integer -o tst tst.c 
/tmp/tst-601e90.o: In function `main':
tst.c:(.text+0x83): undefined reference to `__mulodi4'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

$ clang-5.0 --version
clang version 5.0.0-svn303223-1~exp1 (trunk)

This prevents Firefox from being built with UBSan on 32-bit.
