MySQL Bugs: #108618: ClusterJ test case crash at end

Bug #108618	ClusterJ test case crash at end
Submitted:	26 Sep 2022 16:58	Modified:	20 Oct 2022 19:58
Reporter:	Mikael Ronström	Email Updates:
Status:	Closed	Impact on me:	None
Category:	MySQL Cluster: Cluster (NDB) storage engine	Severity:	S3 (Non-critical)
Version:	8.0.30	OS:	MacOS (12.6)
Assigned to:		CPU Architecture:	ARM (Apple M1 Pro)

Description:
Running test case ./mtr --suite=ndb clusterj
It crashes after successfully completing with a crash in
Ndb_LockCPU_End due to the variable ndb_lock_cpu_mutex
(NdbMutex*) is pointing to address 20. This address is
not a proper address and causes the java process to
crash on a SIGBUS.

The bug isn't present in MySQL Cluster 8.0.23.

How to repeat:
./mtr --suite=ndb clusterj

AS mentioned it only crashes when using Apple M1 Pro CPU and
Mac OS X. It doesn't crash on older Mac OS X using x86 CPU.

Here is the build script used:
cmake -DWITH_DEBUG=0 -DWITH_SSL=$OPENSSL_ROOT -DWITH_NDBCLUSTER=1 -DWITH_NDB_TEST=1 -DWITH_NDBAPI_EXAMPLES=1 -DWITH_ROUTER=0 -DWITH_UNIT_TESTS=1 -DWITH_ERROR_INSERT=1 -DWITH_BOOST=$BOOST_ROOT -DWITH_NDB_JAVA=1 ../
make -j8

It works in MySQL Cluster 8.0.29

Using git bisect discovers that this is the patch that introduces the error:

Reverting this patch fixes the bug.

Hello Mikael,

Thank you for the report and feedback.

Sincerely,

Can you provide compiler and java versions?

I failed to reproduce with below versions (from cmake output):

-- The CXX compiler identification is AppleClang 13.0.0.13000029
-- Java_VERSION: 11.0.12
