Possible SEGFAULT in SaveNexusProcessedTest.testExecOnMuon

[Janik Zikovsky]

Both testExecOnMuon and testExecOnMuonXML are currently disabled. If enabled, they crash on linux in the NexusFileIO::writeNexusProcessedSpectraMap method. The problem appears to be because the nDetectors variable is used to set the size of various arrays but this variable is initialised by calling spectraMap.nElements(), which is not necessarily the number of detectors.

(In [9550]) Re-enable muon tests. The problem was that the test called the algorithm twice and there were member variables that held state that was not cleaned on re-running. Re #2386.

SaveNexusProcessedTest::testExecOnMuonXml now failing on win32 during SaveNexusProcessed execution (line 293). OK on other platforms.

Here's the relevant section of the log from the buildserver:

(In [9556]) Disable test again for now. Re #2386.

Someone over there is going to have to look at the test failure (see above). I don't have a 32 bit windows box here.

Investigated by Martyn:

The xml test is a throwback that should no longer exist. It was from when you might want to save your nexus file as xml, in which case you just called the file bob.xml

The current nexus libraries do not appear to support that anymore, and it was always a mistake to do this anyway as the xml files where HUGE and took forever to write. The test has been removed.
