Interrupt disabled during strcpy()?

Are my eyes deceiving me or are general interrupts disabled for a strcpy? What am I missing here or why?

Using 18F242, PCH 3.212

Easiest way to confirm is compile EX_STR.C

I don't have that version, but I tried it with PCH 3.188 and it does
turn off the GIE bit during strcpy(). Some of the older errata documents
for the 18Fxx2 said you should disable peripheral interrupts during
table write operations, but there are no table writes in strcpy.
It could be just a mistake that got left in the code. You should email
CCS support and let them know about it. Tell them how to duplicate
the problem and show them a section of the .LST file with the bad code
marked. Also tell them your compiler version.
