           Summary: ftell function problems

Hello,

I have a console application for Windows so it's a .exe. The console .exe only
has one function, no GUI or anything. The console application basically
obfuscates a file. Command: ConsoleApp.exe FileName.dylib

I have tried Wine (stable or development builds) and while I can run the
console application fine, and it exits with "Success", the problem is the
output file that is ran using Wine on Linux has a slight difference compared to
the output file that was ran using the same .exe but on Windows.

After investigating the console .exe program, we found out that the whole
problem was due to a piece of code in the .exe "ftell function". Wine
apparently doesn't support it? Or something similar because if we compare the
two output files, the only difference is in here:

 Left is Wine on Linux (Ubuntu) and Right is normal Windows OS output file.

This is the ftell code:

Can you verify this? I did ask on IRC and on the Forums, they told me to submit
a bug report.

Thank you for your time and I hope a fix for this comes as soon as possible so
I can bring my project to life.
