Faulting application name: svchost.exe, Faulting module name: scardhook64.dll

We were seeing these errors on a XenApp 6 farm:

Faulting application name: svchost.exe, version: 6.1.7600.16385, time stamp: 0x4a5bc3c1
Faulting module name: scardhook64.dll, version:, time stamp: 0x4b8ca08e
Exception code: 0xc0000005

The work-around was to disable the Citrix Smart Card hook, of course this can only be done if smart cards are not used in the environment. We used GPP to set these registry entries:
HKLM\Software\Citrix\CtxHook\AppInit_Dlls\Smart Card Hook\Flag = 0
HKLM\Software\Wow6432Node\Citrix\CtxHook\AppInit_Dlls\Smart Card Hook\Flag = 0
Note that the default values for these registry settings is 0x80000000.
