problems with crtdll

I have a file system Filter on WinNT that requires to parse strings. I tried
using the wcstok function…But it required me to link the crtdll.lib while
building the driver…When i try to start the driver it fails with a message
code 0xc0000034
what could be the problem and what is a preferred workaround (apart from
implementing the wcstok function ) ??

TIA
