Quite possibly this is yet another obscure bug involving dumping. I hope 
the portable dumper will be merged soon. Could you please remind me what 
the remaining trouble spots are with pdumper, i.e., the issues that are 
preventing merging that branch in?

Anyway, I struggled a bit with Joseph's report (trying lots of ways to 
build Emacs master on Fedora 28) and managed to reproduce a similar 
problem that does indeed involve dumping. I installed into Emacs master 
the attached patch, which fixed that bug for me. Joseph, please try the 
latest master, and if that doesn't work then GDB may well be your friend 
(though it may not be; dumping leads to reaaaally obscure problems).
