Got a crash log from a customer:

which is typical for memory problems. I then made him a version, which looks at available and free memory:

and immediately after the app crashes. So this doesn’t look like a memory problem. And the crash seems to happen for the same mail. The new version also replaces the ReplaceAll function with a very simple self-made function.
Original:
theMailFields.MessageRawData = ReplaceAll(theMailFields.MessageRawData, Encodings.ASCII.Chr(9), "")Replacement:
dim theResult(-1) as string
for currentChar as Integer = 0 to Len(theMailFields.MessageRawData) - 1
dim theChar as String = Mid(theMailFields.MessageRawData, currentChar, 1)
if theChar <> Chr(9) then theResult.Append theChar
next
theMailFields.MessageRawData = Join(theResult, "")
And now the customer gets the following crash:

Does anyone have an idea what is happening here?
