[fpc-devel] Might need some help with this one

[J. Gareth Moreton]

(I'm on the Raspberry PI, so I'm posting this via my Webmail, so the e-mail chain may get messed up 
in the logs. Sorry)

BREAKTHROUGH!  This issue is not isolated to x86_64-win64.  I have just reproduced it on aarch64-
linux.

I'm starting to suspect that i38053, i38055 and i38129 are all related.
