debugstr buffer overflow

[Stefan Leichter]

Hello,

attached is a piece of a logfile that shows a buffer overflow of the debugstr. 
For my understanding the function should have only two parameters! is this 
right? What may cause this problem? Any ideas? Hints to trace the problem?

Thanks
Stefan

For the record:
logfile generated by installing mdac_type.exe (2.8) with current wine (cvs) on
