I started a new attempt. On 
http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=15fa8de1ae3228413fde95e583008d9b9f19e7c7
 I found this number. I patched a MacPorts control file and so port used the 
command '/usr/bin/git checkout -q 15fa8de1ae3228413fde95e583008d9b9f19e7c7' to 
fetch the sources. GNU Emacs 27.0.50 could be build, and it shows here on my 
Mac still the same error with the "Invalid hash table rehash size."

I also have two X servers installed (actually three). The one is XQuartz 
2.7.11, which comes inside an Apple installer package, the other is X11, built 
from source by port from the sources of the packages xorg-server 1.18.4 or 
xorg-server-devel 1.19.99.1. What I can observe is that GNU Emacsen 26.x or 
27.0.50 built in one X server do *not* run in that X server ("Invalid hash 
table rehash size"), but they *do* in the other.
