The bug could indeed be reproduced with gcc 9.1.1, and turned out to be caused
by -ffinite-math-only which -Ofast includes. This option allows the compiler to
assume that no number is infinity or NaN.
This causes printing ±Inf to misbehave since the standard isinf function now
always returns false, and 1.0e+INF is printed as "inf" when generating the
constant pool in the byte-compiled function. When this byte-code is loaded, the
value is read back as the lisp symbol `inf' which caused the error we saw.
The precise location is in the initialisation of math-largest-emacs-expt; the
error occurs during load time, but the damage was already done by
float_to_string when calc-math.elc was generated.
In other words, the route to the error was somewhat roundabout, but it looks
like there is no actual bug in Emacs nor in gcc. But at least I didn't know
that, and was enlightened by the result.
