Comment (by cypherpunks):

 >Doesn't crash for me (OP)
 Ok.

 Part of code in disassembler before (nssckbi.dll):
 {{{
 69BCD189: 55                   push        ebp
 69BCD18A: 89E5                 mov         ebp,esp
 69BCD18C: 83EC18               sub         esp,018
 69BCD18F: C7442404B8E8BC69     mov         d,[esp][4],069BCE8B8
 69BCD197: C70424244ABD69       mov         d,[esp],069BD4A24
 69BCD19E: E835170000           call        PR_NewThreadPrivateIndex
 69BCD1A3: C9                   leave
 69BCD1A4: C3                   retn
 }}}
 After (NSSCKBI_patched.DLL):
 {{{
 69BCD189: 55                     push        ebp
 69BCD18A: 89E5                   mov         ebp,esp
 69BCD18C: 83EC10                 sub         esp,010
 69BCD18F: 909090                 nop
 69BCD192: A13C62C269             mov         eax,PR_Free
 69BCD197: 50                     push        eax
 69BCD198: 90                     nop
 69BCD199: 68244ABD69             push        069BD4A24
 69BCD19E: E835170000             call        PR_NewThreadPrivateIndex
 69BCD1A3: C9                     leave
 69BCD1A4: C3                     retn
 }}}
