Wine's GetOpenFileNameW/GetSaveFileNameW seems to crash when encountering a
very long path name (i.e. longer than MAX_PATH characters).

What version of OpenMPT are you using? It crashes when you select a file in the
dialog and press OK or crashes when you browse to a too deep folder?

Anyway, wine 1.6.2 is very old. Please update to wine 1.8-rc2 and try again.

The version of OpenMPT does not matter - the application crashes *in the file
browser* before it passes back control to the program.
1.6.2 is still the default on Ubuntu LTS so I'm not really able to upgrade at
the moment.

This was the file I used to test:
35125d37407edfeb24fd5db47124972324f9266a OpenMPT-1.25.04.00-Setup.exe

I installed the program then launched it and opened one of the songs from the
examples folder, this works.

Then I created a very long (> 255 characters) sequence of directories with an
example file inside and the application closed.

Does it work in Windows in the same conditions?

It still happens with v1.9.0, but there might be more to the issue. It does
indeed not appear if you just create an overly long filename. The issue appears
to happen if the overly long filename is found in a shared virtualbox folder.

I've created a virtualbox shared folder and then mounted it like this in a
Xubuntu VM:
mkdir ~/music
sudo mount -t vboxsf -o uid=$UID,gid=$(id -g) E_DRIVE ~/music
In this folder, I have placed an overly long directory name
("1xxxxxxxxx2xxxxxxxxx3xxxxxxxxx4xxxxxxxxx5xxxxxxxxx6xxxxxxxxx7xxxxxxxxx8xxxxxxxxx9xxxxxxxxx0xxxxxxxxx1xxxxxxxxx2xxxxxxxxx3xxxxxxxxx4xxxxxxxxx5xxxxxxxxx6xxxxxxxxx7xxxxxxxxx8xxxxxxxxx9xxxxxxxxx0xxxxxxxxx1xxxxxxxxx2xxxxxxxxx3xxxxxxxxx4xxxxxxxxx5xxx"
for testing) which then crashes the Wine explorer.

Could be dupe or related to bug 39867.

If wine uses some point of MAX_PATH I think it has max value of 255 or 256 +1.

There are 2-3 similar bugs to this currently.
