[PATCH] PR 78534, 83704 Large character lengths

[Dominique d'Humières]

I use x86_64-apple-darwin17 and I run the test with -m32. Without the patch, a plain compilation leads to four errors and a timing

0.011u 0.008s 0:00.02 50.0%	0+0k 0+0io 13pf+0w

With the patch I get the four errors plus "Result of LEN overflows its kind » and a timing much slower

12.454u 21.185s 0:35.29 95.2%	0+0k 0+0io 955pf+0w
