I can confirm this is the case from my experiments compiling xplor-nih with
-fsanitize=address. This code is habitually miscompiled by gfortran at the
higher optimizations levels. The addition of the -fsanitize=address flag to
the build suppresses most of the xplor-nih testsuite failures indicating that
it has changed the code optimization in gfortran. Is there any chance of moving
the asan pass or is that definitely stage 1 material?
