SYMPTOMS
Using FOR /F in a batch command file may cause an access violation in Cmd.exe. This behavior can occur when you use a statement similar to the following sample statement if the file has been passed as parameter %1 and contains a single line with more than 256 characters:

for /f &quot;tokens=2,3,5,8,10 delims=,&quot; %%i in (%1) do if %%k==10 call :loop %%i %%j %%l &quot;%%m&quot;



CAUSE
This behavior occurs because Cmd.exe corrupts the heap while it is reading the token file.
