I having problems getting Emacs to build on commit 5c3dba24ef, after
cloning and running make, I get:
make[2]: Entering directory '/home/fede/Workspace/emacs/lisp'
ELC calc/calc-aent.elc
In toplevel form:
calc/calc-aent.el:28:1:Error: Arithmetic range error: "expt", 10, 9
Makefile:301: recipe for target 'calc/calc-aent.elc' failed
make[2]: *** [calc/calc-aent.elc] Error 1
make[2]: Leaving directory '/home/fede/Workspace/emacs/lisp'

make[1]: *** [compile-main] Error 2
make[1]: Leaving directory '/home/fede/Workspace/emacs/lisp'

In case it matters, I'm on a x86-64 Celeron J4005 processor, using Ubuntu 18.04.

Thanks for reporting it, as it didn't happen on the platform I was testing with.
I installed the attached, which should fix it.
