Bad allocation error

[teognost]

Hi
I have got this error:

"Error firing vbld_StepDone event: Error in Step (VBScript) script code at Line 17, Column 1 (bad allocation)"

where the code referred in vbld_StepDone event is:
strLastStepOutput=Application.ExpandMacros("%LASTS TEP_OUTPUT%")

I checked and Application.Options.MaxStepOutputLength = 0
I checked and the output of last step is quite big,can this be the cause?
Any idea how to solve this issue?
