Hi,
Thanks very much!
I find the following crash
When I run this command:
I see the following crash below on a x8664 system:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=22.04
DISTRIB_CODENAME=jammy
DISTRIB_DESCRIPTION="Ubuntu Jammy Jellyfish"
If I apply the following patch the crash goes away.
diff --git a/src/plugins/SqueakSSL/SqueakSSL.c b/src/plugins/SqueakSSL/SqueakSSL.c

}
Sorry, I realize that patch is quite trivial and just removes the added feature.
I also see a crash running the same command on Raspberry PIs running the latest OS based on Debian 12.4.
Thanks

Log Message:
-----------
CogVM source as per VMMaker.oscog-eem.3349
Integrate VMMaker.threaded-LM.3339, 3341, 3342 & 3343.
Make vmThread>>#state an atomic_int
Allow -1 to be set as vmOwner.
This is currently used by the heartbeat thread.
In future this will be used by the ownVMFromUnidentifiedThread function.
This combines well with the additional change that makes disownVM return a CogVMThread* disguised as void*.
We can then ensure that the threads variable is only ever accessed by the vm owner.
Fix multiple issues regarding thread safety
1. vmOwner -1 can be used to lock the VM to a thread that is not a classical "VM Thread" (e.g. the heartbeat thread).
2. maxWaitingPriority is now an atomic.
Fix thread switch accidentally disowning the VM which causes an incorrect preemption.
Allow thread switching during the SqueakSSL primitiveConnect.
Rename ownerIndex to threadAffinity.
And update revertIfEssentiallyUnchanged to cope with the CryptographyPlugins.
