I notice that when I 'org-reload' C-c C-x ! then the whole
compilation starts again even when its already compiled. Somewhere it
misses that. I didn't investigate this any further. Maybe its intended
behavior because org-mode forces to byte-compile itself.

Might be smarter to store a hash over the source .el or .elc in the .eln
metadata and prevent recompilation when it was already compiled. In fact
all .eln could be addressed by these hashes with some directory
restructuring (I dont go into detail here, this would be another
feature).

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

I'm still not sure if we should switch off deferred compilation while
loading with MUST-SUFFIX but given 02e3ffad6d solves this issue I'm
closing the bug.

Thanks Christian for reporting it.
