When running on macOS aarch64 (XCode15) with ubsan-enabled binaries, the test 
compiler/profiling/TestProfileCounterOverflow.java
generates this error :

The out of range happens here :

909  int ciMethod::scale_count(int count, float prof_factor) {
......
916      if (counter_life > 0) {
917        count = (int)((double)count * prof_factor * method_life / counter_life + 0.5);

Same can be seen on AIX when running with ubsan - enabled binaries : compiler/profiling/TestProfileCounterOverflow.java : /srcdir/jdk/src/hotspot/share/ci/ciMethod.cpp:917:20: runtime error: 2.68435e+09 is outside the range of representable values of type 'int'

ILW = Possibly setting wrong scale count due to cast overflow from double to int (might lead to inefficient code), low?, no workaround but disable compilation of affected method = MLM = P4
