The problem is in function SHELL_execute in line 1714 and 1717.


            lstrcpynW(wfileName, sei_tmp.lpFile,sizeof(wfileName));
        }
    } else
        lstrcpynW(wfileName, sei_tmp.lpFile,sizeof(wfileName));

    lpFile = wfileName;


There is a strcpyW from sei_tmp.lpFile (wich size we don't know) to wfileName
with fixed length = MAX_PATH.

As a result wfileName by accident overwrites lpstrProtocol passed as argument
"key" to SHELL_FindExecutable. That's why in function SHELL_FindExecutable
line:

if (key) *key = '\0';

cuts my long argument.

How should I solve this problem?

Using lstrcpynW instead of strcpyW doesn't solve my problem, because it will
still cut my argument.
