JDK-8329103 - assert(!thread->in_asgct()) failed during multi-mode profiling
Description
This is another manifestation of the same issue as in JDK-8329103. This time, however, production JVM crashes, not a debug build.
The reason is `in_asgct` flag is not reset correctly when AsyncGetCallTrace() is called recursively. The fix is similar to JDK-8329103.
Comments
[jdk8u-fix-request] Approval Request from Andrei Pangin Low risk yet important fix for profiling robustness. Affects only AsyncGetCallTrace code.
