invalid pcre ccall error message

Might be from the depwarn? Just overdubbing the depwarn doesn't trigger it though...

I think ccall has specific linearization requirements for the IR and it is checking if the arguments are constant, maybe we added a level of indirection here that messes that up?

We did emit calls that messed that up before (#52), but I thought I had fixed it...
