[Bug 45309] New: Program runs fine in Wine, but dies in Wine-dbg

https://bugs.winehq.org/show_bug.cgi?id=45309

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]
          Reporter: [e-mail]
      Distribution: ---

  --> https://bugs.winehq.org/attachment.cgi?id=61583
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.

--- Comment #1 from Zebediah Figura  ---
Most of this is valid behaviour. Programs throw and catch their own exceptions
all of the time. You can ignore certain types of exceptions with e.g. 'handle
SIGSEGV noprint', although this may also prevent breaking on useful exceptions.

That it fails subsequently may be a bug, although it may be a matter of timing
or something similar.

Renaming threads is a debugging aid, so of course it should show up in winedbg
and not otherwise.

Hello Dave,

I can't reproduce this, even with old Wine 3.9.

Adding stable link via Internet Archive:

http://download.adobe.com/pub/adobe/dng/win/DNGConverter_10_3.exe

Using RAW camera image examples from different vendors:

https://rawsamples.ch/index.php/en/

Selected directory with the samples and started conversion process.

If you can still reproduce it please provide exact steps, i.e. which kind of
RAW images. Also information how Wine was built (distro + GCC version).

If you can't reproduce or are not interested anymore I propose to resolve the
ticket as 'ABANDONED'.

Not sure what the original reason for debugging this app was but there are
certainly better alternatives to Wine's builtin debugging aid. It's like using
a stone axe when you could use a 400+ piece Mechanic's Tool Set ^^ But yay,
tools are not that important. Knowledge and experience are the most important
thing.
