Hi, thanks for your suggestions, it looks like it was rpmfusion just
happened to have a difference in CFLAGS used, which happened to trigger a
bug in this package.  Dosemu uses some attribute((constructor)) functions
that get called before main. The order isn't known (for newer GCCs you can
set priorities but they are not used). Somehow the RPMFusion build ended up
with an order that triggered the hang (that has, in principle been present
in dosemu for many years), a linked-list where an element referenced itself.

Is there any way to see what URL's are being used by mock for the builder?
I want to build in mock with exactly the same repos as rpmfusion is using.
