Most of this message's fields are not understood. Currently, we have the following information:

[code]
Message ID:  0x5D
Message Name: SID_REPORTCRASH
Direction: Client -> Server (Sent)
Used By: Diablo II, Diablo II LOD, Warcraft III, Warcraft III: TFT
Format:
(DWORD) 0x10A0027
(DWORD) Exception code
(DWORD) Unknown
(DWORD) Unknown

Remarks: When the game crashes, (usually) a file named Crashdump is created. If this
file exists at the next logon, the contents of it are sent to Battle.net in
this message. For Diablo II: First DWORD is a constant (version?), seen in
Fog.dll, last two are unknown. All calls to Fog_10052 result in the output
of Crashdump.

More research is required.
