Hi,

I built the latest R3-14-2_branch against linux-x86_64 and ran a few
tests in libCom/tests. All tests were successful; except
"epicsMessageQueueTestHost"

==============================================================================
[williams@sns-hp-eval1 O.linux-x86_64]$ epicsMessageQueueTestHost
Simple single-thread tests.
Should have 1 used -- Message Queue Used:1  Slots:4
Should have 2 used -- Message Queue Used:2  Slots:4
Should have 3 used -- Message Queue Used:3  Slots:4
Should have 4 used -- Message Queue Used:4  Slots:4
Test sender timeout.
Should have 1 used -- Message Queue Used:1  Slots:4
Should have 2 used -- Message Queue Used:2  Slots:4
Should have 3 used -- Message Queue Used:3  Slots:4
Should have 4 used -- Message Queue Used:4  Slots:4
Test receiver with timeout.
Single receiver with invalid size, single sender tests.

Single receiver, single sender tests.
Segmentation fault

========== Results from GDB ============================================

Core was generated by `epicsMessageQueueTestHost'.
Program terminated with signal 11, Segmentation fault.
