Bug ID: 52488
           Summary: Nota Bene crashes at the end of install with denormal
                    float operand exception
           Product: Wine
           Version: 7.1
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

Follow up to bug 12732. Now that the thunks are not getting freed anymore, this
is the next issue plaguing the installer.
Note that it works fine in winevdm from otya128 and we have permissions to port
fixes back to Wine.
