VirtualBox crashes on Solaris host when using Share Folder on WinXP guest => Fixed in 1.6.4

[Renaud]

I've recompiled VirtualBox from Mar-15-2008 source trunk on Solaris Nevada build 82.

If I add a share folder to my WinXP guest, VB crashes with the following stack (see next comment).

It's 100% reproducible.

I believe this is happening when WinXP tries to reconnect the network drive.

Try again with 1.6.0 and report back if it's still relevant. Thanks.

[Renaud]

Problem still exists with 1.6.0 although the stack trace is different:

[Sander van Leeuwen]

Did you build it yourself again? If so please try our binary version to rule out an issue with self-building.

[Renaud]

I didn't build it myself this time. I've tried the binary version 1.6.0. The crash occured when I double clicked on the network drive.

[Ramshankar Venkataraman]

Tried here with WinXP Pro and adding a shared folder. I'm unable to reproduce the crash. But also using "net x:\vboxwebsvr\<the-share-name>" doesn't work.

[Ramshankar Venkataraman]

This is fixed in internal SVN. Thank you for reporting.
