Hi Christian,

I assume deferred-compilation is non nil.

I managed to reproduce the issue and 02e3ffad6d solves it for me.

The only thing I'm uncertain is if generally speaking we should disable
the deferred compilation trigger when a load with MUST-SUFFIX non-nil is
performed.  Currently we are not doing that but I'm asking myself if
this would be appropriate.

Thanks

  Andrea
