Well, I figured out why.  This was a bug in Twisted's, which 
has a function _check_header that is supposed to invoke the compiler on 
a tiny test module to make sure the module being built will build 

The new compiler is constructed with new_compiler(), but no arguments 
were passed to it; it was this invocation that fails with the error 
message I was getting.  This bug was introduced some time ago; I'm not 
sure why I didn't see it before now.

Using self.compiler instead worked (there's no need to call 
new_compiler() when it's already been done for you).
