Bug ID: 52256
           Summary: Current working directory reset to "/" executing a
                    winegcc/wineg++ compiled program
           Product: Wine
           Version: 6.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winelib
          Assignee: wine-bugs@winehq.org
          Reporter: sacrom@gmail.com
      Distribution: ---
This is exactly the same bug (from the behaviour point of view) than:
https://bugs.winehq.org/show_bug.cgi?id=49545
Fixed by commit:

It seems a "regression" between WINE 6.5 & WINE 6.6 happened.
Since Wine version 6.6 the current working directory is reset to
"/" when executing a winegcc/wineg++ generated program (winelib). While in Wine
6.5 and
previous versions (from 6.0 onwards) the current working directory was the
directory where the
command was executed from.

Here you can see the program, compilation and result using the latest WINE 7.0
RC2:
[sc@generic_linux1_64]/sc/tmp/wine$ wine --version
wine-7.0-rc2
[sc@generic_linux1_64]/sc/tmp/wine$ cat showdir.c 
#include <unistd.h>
#include <stdio.h>
void main(void)
{
    char buf[256];
getcwd(buf, sizeof(buf));
    fprintf(stderr, "getcwd() => %s\n", buf);
}
[sc@generic_linux1_64]/sc/tmp/wine$ winegcc -o showdir_wine showdir.c
[sc@generic_linux1_64]/sc/tmp/wine$ ./showdir_wine.exe
getcwd() => /
Searching for the WINE version, that introduced the difference:
WINE 6.5 WORKING
----------------
[sc@generic_linux1_64]/sc/tmp/wine$ ./showdir_wine.exe
getcwd() => /sc/tmp/wine
[sc@generic_linux1_64]/sc/tmp/wine$ wine --version
wine-6.5
WINE 6.6 NOT WORKING
--------------------
[sc@generic_linux1_64]/sc/tmp/wine$ ./showdir_wine.exe
getcwd() => /
[sc@generic_linux1_64]/sc/tmp/wine$ wine --version
wine-6.6
