Bug ID: 45309
           Summary: Program runs fine in Wine, but dies in Wine-dbg
           Product: Wine
           Version: 3.9
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winedbg
          Assignee: [e-mail]

winedbg trace, only showing the first two exceptions. In wine, only "fixme"
messages appear, and the program runs perfectly.

I have a program that runs flawlessly in Wine, including the generation of an
output file whose correctness can be independently verified.

However, when I run the same program in Wine-dbg, it generates dozens of
floating point exceptions: stack error, inexact result, and sometimes overflow
and divide by zero. If I "continue" through all these exceptions, the program
opens a window saying that the program "has encountered a serious problem and
needs to close", or "There was an unknown error", and no output file is
generated.

Also notice that the "Thread ID=0034 renamed using MS VC6 extension" messages
only appear with winedbg, not wine.

The program being run is Adobe DNG Converter 10.3, and I deleted my .wine
directory before installing it. I tried converting various raw photos and all
exhibited this behavior.
