Description
From ticket #2269
I have been trying to load a small event file that I have saved first (using the data in Mantid/Test/Data/sns_event_prenexus/SEQ_TS_2009_01_06.dat)
This is a very small file, but on loading I get a bad allocation on windows, I have over 2GB available memory, and the original ws only took 9,350KB.
All seems okay on Linux.

This came from Nick, it was this file: Mantid/Test/Data/sns_event_prenexus/SEQ_TS_2009_01_06.dat
Which actually, now looking at it, isn't an event file is it?

No, it is a mapping file; it gave a few errors during loading but still loaded something (both files are pure binary so it is possible to load them even if the results are meaningless). I was able to save and load back on Linux without a crash.

Michael Whitty error report:
File saved can not be loaded (in [9515])
Steps to reproduce:
- Load CNCS_7860_event.nxs using LoadEventNexus
- Right click on workspace, select 'Save Nexus'
- Try to run either LoadNexus or LoadNexusProcessed, you receive error message "bad allocation".

I've also tried this with a correct prenexus file, and an event nexus file as the original data, same effect. Bad alloc on reloading the data.
