Could you attach your /etc/fstab and the output from 'mount' please?

The devices are all mounted on startup. Until version 1.7.45 the command has
worked without any problems. I put the version 1.7.48 because it's where I've
tried, but most likely in the 1.7.46 and 1.7.47 not working. Write Wine
installation manuals, and all put this command to enable the devices. Using
Fluxbox. Example:

http://manualinux.eu/psp7.html

This command has always worked so far.

Could you please run a regression test?

I compiled packages of different versions of wine and the results are as
follows:

configuration parameters = ./configure --prefix=/opt/wine-${VERSION}
--disable-tests --without-gstreamer
dependencies = full

Compiler= Clang 3.6.2

wine-1.7.45 -> KO
wine-1.7.44 -> KO
wine-1.7.40 -> KO
wine-1.7.35 -> KO

They worked before. I always use Clang to compile wine.

Compiler= GCC 5.2.0

wine-1.7.48 -> KO

Compiler= GCC 4.9.3

wine-1.7.48 -> KO

To verify that it is not a problem specific to my system, I tested on FreeBSD
10.1 (amd64), installing the package i386-wine-devel-1.7.47 and the command
does not work either. With the 64-bit version, wine-staging-1.7.48, does not
work either.

And I've also tested distributions precompiled packages.

Slackware 14.1

wine-1.7.47 -> OK

OpenMandriva 2014.2

wine-staging-1.7.42 -> hangs in the two modes (graphic and console)

OpenSUSE 13.2

wine-1.7.28 -> OK

...so it isn't a regression at all?

For my part I close this, but the problem is still there. I have nothing more
to add.

Thanks for your attention.

It looks like you have more drives than it's possible to mount, winecfg error
seems clear in saying that it is running out of letters.

Please attach the output of:

I think the driver letter maximum value has been hard coded into 32. I looked
winecfg source code not so long ago.

It's lower than that.

struct drive drives[26]; /* one for each drive letter */

There are only 26 letters in the English alphabet. Windows has the same limit
on drive letters; above 26, you have to mount the volume to a directory.

In graphics mode it works perfectly. In Slackware 14.1 with the same fstab the
command works. In FreeBSD 10.1 (amd64) with another smaller fstab the command
fails.

Thanks, please also attach the same log when running graphically since it works
for comparison.

The log is clear as expected, since Z is a special drive the last available
letter is Y, so it reaches the drive limit at mount point "/dev/sdc2
/mnt/win_h". I expect the graphical mode to run a slightly different code path.

Ok, thanks again. As expected wine is running out of letters in both console
and GUI modes. The difference is that when run in GUI mode it will always apply
the drive changes even if not all drives could be mapped, while in the console
mode (-d) it will only apply the changes if all drives could be mapped.

So we have a bug because there is an inconsistency between the console and GUI.
Should we change the GUI or console? That requires some discussion.
