Description
ADDITIONAL SYSTEM INFORMATION :
# JRE version: OpenJDK Runtime Environment (8.0_392) (build 1.8.0_392-internal-fastdebug--b00)
# Java VM: OpenJDK 64-Bit Server VM (25.392-b00-fastdebug compiled mode linux-amd64 compressed oops)

A DESCRIPTION OF THE PROBLEM :
I ran a modified regression test case on JDK8u392 and found that the JVM crashed with -Xcomp -XX:-TieredCompilation options.

ILW: High (crash, in debug) L (debug build assert, broken invariant) M (run the application by excluding the problematic method from compilation) Rising the priority to P3.

JDK-8288559 was supposed to fix this by backporting JDK-8210389 but since 8u381 is still affected, it must be a different issue.

Issue is reproduced. Crash is observed on JDK 8 GA build with java -Xcomp -XX:-TieredCompilation compiler.c2.TestRemoveMemBarPrecEdge and Crash is observed on 8u381 debug build with java -XX:-TieredCompilation compiler.c2.TestRemoveMemBarPrecEdge OS: Windows 10 JDK 8u381: Fail JDK 11.0.20: Pass JDK 17.0.8 : Pass JDK 21 : Pass ILW = Crash, reproducible on GA build, no known workaround yet = MLM = P4 Moving it to dev team for further analysis
