[Opendnssec-develop] Test platform freebsd 9 amd64 core dump

[Sara Dickinson]

Hi All, 

We are having more problems with the strange segmentation fault seen _only_ on the 64bit FreeBSD machine. One of the enforcer tests is now persistently failing with the first core dump below and has had to be disabled and another signer test is failing intermittently with the same problem. The other 2 core dumps have also been seen intermittently on other tests or checks on this machine. All originate in _pthread_mutex_init_calloc_cb () so the belief is it a strange freebsd/pthread problem but nothing jumps out when you Google the problem. 

Does anyone have any bright ideas as to how we could workaround this? (At the moment the ax_pthread.m4 macro configures the threading library.)

Sara.
