Hello folks,

although I can't reproduce your crash I can at least confirm that Wine's PDB
parser chokes on the PDB files shipped with Unity.

I had the pleasure to debug some nasty random freeze (Mono is always up for
surprises) and 'dbghelp' does indeed not like those PDBs, hence they have to be
renamed or moved out of the way:

--- snip ---
$ pwd
/home/focht/wine-apps/unity3d/drive_c/Program Files/Unity/Editor

$ ls -la *.pdb
-rw-rw-r--. 1 focht focht   7130112 Nov 18 17:37 mono.pdb
-rw-rw-r--. 1 focht focht 171617280 Nov 18 17:56 Unity.pdb
--- snip ---

There are a few other PDB related bugs though, such as bug 34990

NOTE: Fixing the assert() problem won't probably help you since it's triggered
by some crash elsewhere.

Used the following 'winetricks' extension verb:
https://github.com/Unity3D-Wine-Support/Unity3D-on-Wine/blob/master/unity3d.verb

--- snip ---
$ winetricks --no-isolate -q unity3d
--- snip ---

$ sha1sum UnitySetup-4.6.0.exe 
5cc7a85e186c965d230bcc7a2a463d92fbc2f7fc  UnitySetup-4.6.0.exe

$ du -sh UnitySetup-4.6.0.exe 
1.3G    UnitySetup-4.6.0.exe

$ wine --version
wine-1.7.34-74-gcf92569

Regards
