For some reason your mail was only in the archive not in my inbox. Let's see if this works out: Do these debug helpers exists in Zulu VM which is based on OpenJDK? https://docs.azul.com/core/ Azul Zulu Builds of OpenJDK docs.azul.com docs.azul.com If yes, how to activate them? Do they produce full stack frames with parameters etc. ? ________________________________ From: Andrew Haley > Sent: Thursday, July 20, 2023 8:55 PM To: Roger Phillips ; gdb@sourceware.org Subject: Re: Using symbol map file with gdb? Just in case you didn't already know this: If your JVM is HotSpot then it contains the debug helpers to handle debugging generated/interpreted code.
