Description (last modified by Stuart Campbell) (diff)

This is a major 'gotcha'. Roughly 200 tests fail when running from ctest. The xml files generated by the tests say that they pass (random sampling in DataHandling, but ctest says they failed. Until this is sorted out there will be a major problem for people using fedora 14 and ubuntu 11.04 to develop mantid.

The reason that most of the tests fail is down to a crash in dlclose() 

Inconsistency detected by ld.so: dl-close.c: 743: _dl_close: Assertion `map->l_init_called' failed!

Investigating further...

It looks like this is a bug in glibc. It is trying to call the destructors after dlclose, rather than before. This of course might not be the problem but it looks likely.

The recommended workaround is to just not call dlclose().
