--- Comment #2 from Eugene Rozenfeld <erozen at microsoft dot com> ---
When -gstatement-frontiers is on, the IR coming from the front end may be
different with and without debug information turned on. That may cause e.g.,
different discriminator values and -fcompare-debug failures.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100733.
In https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=f1adf45b17f7f1ed I added
-gno-statement-frontiers to gcc/testsuite/c-c++-common/ubsan/pr85213.c
b/gcc/testsuite/c-c++-common/ubsan/pr85213.c to work around this problem for
that test.

It looks like r14-5257-g61d2b4746300a604469df15789194d0a7c73791b fixes this.
