OK (as the documentation says "[...] that might overflow the destination buffer).

With MPFR, the code is in an "else" branch, already with a reduced range. However, this time, I did not use -O2 to enable VRP (I was working on a different issue, but had to use -Werror=format to change the behavior of the configure script); that was my mistake. Then I found the inconsistency between "e" and "e - 1", so I did not look further.
