D 2.066.1: Assertion failure: '0' on line 2022 in file 'mtype.c'

[Andre via Digitalmars-d]

Hi,

after the update from 2.066 to 2.066.1
DMD gives following output:

Assertion failure: '0' on line 2022 in file 'mtype.c'
abnormal program termination

Unfortunatelly I do not know how to create a reproducible
example as the error occurs in a huge application.

DMD doesn't give me more information. I try to find out more
(reproducible example).

Kind regards
André
