Hi –

I use IBO 4.9.14.55 with Delphi XE in a Windows service application.

This bug has been reported to me a handful times, but I can’t reproduce it. Stack trace below.

It happens when opening a TIBOQuery.

Although it happens during memory allocation, there does not seem to any abnormal memory consumption.

Is it a known IBO bug? Thanks for any help.
