Seen when running vmTestbase/nsk/sysdict/vm/stress/btree/btree011/btree011.java

The crash shown above is happening here: https://github.com/openjdk/jdk/blob/287b24322135b54641f013970c4545ce069c4350/src/hotspot/share/jvmci/jvmciEnv.cpp#L1673
Just prior to the crash, the caller also calls `cb->is_nmethod()`: https://github.com/openjdk/jdk/blob/287b24322135b54641f013970c4545ce069c4350/src/hotspot/share/jvmci/jvmciCompilerToVM.cpp#L1135

This implies that in between these 2 calls, at least one safepoint has occurred during which the CodeBlob pointed to by `cb` was reclaimed and so `cb` is pointing at random memory. There are safepoints for each call back into libgraal since they are JNI calls. The most obvious candidates in this case are https://github.com/openjdk/jdk/blob/287b24322135b54641f013970c4545ce069c4350/src/hotspot/share/jvmci/jvmciEnv.cpp#L1665 and https://github.com/openjdk/jdk/blob/287b24322135b54641f013970c4545ce069c4350/src/hotspot/share/jvmci/jvmciEnv.cpp#L1668 .
