| Unloading DLL that allocated TLS index that was not freed |
Application Verifier break message
Unloading DLL that allocated TLS index that was not freed.
Probable cause
This stop is generated if a DLL that allocated a TLS index is being unloaded before freeing that TLS index.
Information displayed by Application Verifier
Parameter1 - TLS index
Parameter2 - Address of the code that allocated this TLS index
Parameter3 - DLL name address. Use du to dump it
Parameter4 - DLL base address
Description - Unloading DLL that allocated TLS index that was not freed
Additional information
Verifier stop code 0350.
To debug this stop:
du parameter3 - display the name of the culprit DLL;
.reload xxx.dll=parameter4 - reload symbols for the culprit DLL (if needed) xxx.dll is the name of the DLL displayed in the above step;
u parameter2 - disassemble the code that allocated the TLS. This should point to the function that allocated the TLS but forgot to free it before the DLL was unloaded.
