A DESCRIPTION OF THE PROBLEM :
Since mid-March, we noticed occasional SIGSEGVs in PhaseIdealLoop::identical_backtoback_ifs, about once a week, in our Java-Applications. The error log indicates an error in the C2 compiler, either in oracle.net.resolver.AddrResolution::resolveTNSAddress or in oracle.net.resolver.NavAddress::navigate

REGRESSION : Last worked in version 17

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Can't reproduce it yet, happens about once a week in all our Java Applications

EXPECTED VERSUS ACTUAL BEHAVIOR :
