queuing_test fails on macos, gcc-12, openmp enabled

[ohm314]

Describe the issue

Following the developer build workflow on macos (intel) with gcc-12 and otherwise default flags, I get the test queuing_test failing with following message:

4: unknown location:0: fatal error: in "threaddata_interthread_send": signal: SIGSEGV, si_code: 0 (memory access violation at address: 0x00000000)
4: /Users/awile/projects/cellular/corenrn_development/nrn/external/coreneuron/tests/unit/queueing/test_queueing.cpp:86: last checkpoint
4: 
4: *** 1 failure is detected in the test module "QueueingTest"

To Reproduce

• on macos (intel) with gcc-12 packages available
• clone nrn
• build with coreneuron enabled, all flags default but explicitly use gcc 12
• run ctest

Expected behavior
It should not fail
