FindPeaks crash in Debug

[KarlPalmen]

This ticket is blocks : TRAC10052

If you run the following script

ws = CreateSampleWorkspace(Function="User Defined", UserDefinedFunction="name=LinearBackground, \
   A0=0.3;name=Gaussian, PeakCentre=5, Height=10, Sigma=0.7", NumBanks=1, BankPixelWidth=1, XMin=0, XMax=10, BinWidth=0.1)

table = FindPeaks(InputWorkspace='ws', FWHM='20')

in the Debug build, Mantid crashes, but it works OK in Release build.
The crash occurs in a loop of FindPeaks::estimatePeakParameters created in the course of ticket http://trac.mantidproject.org/mantid/ticket/7789, where a call to VECY[100] is made despite it having only 100 elements [0:99].
