Profiling crashes in NMethod::isNMethod with JDK 23-ea #923
Description
I'm using async-profiler with the latest JDK built from git; recently the the JDK started crashing with:
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x000071cbb0806ecf, pid=928720, tid=928742
#
# JRE version: OpenJDK Runtime Environment (23.0) (build 23-internal-adhoc.daniel.jdk)
# Java VM: OpenJDK 64-Bit Server VM (23-internal-adhoc.daniel.jdk, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64)
# Problematic frame:
# C [libasyncProfiler.so+0x6ecf] NMethod::isNMethod()+0x1f
The crashes started after this commit. I tried profiler versions 2.9 and 3.0, same crash in both cases. I'm using JMH to run the profiler.
