Description Cheyenne Wills 2020-07-13 23:05:05 UTC

A bug was reported to upstream dealing with large numbers (the test lgint fails)

a := 2 ^63
b := -a
write(b)

Displays garbage output.

The problem was due with gcc 9 (and later) optimizations.

Reproducible: Always

Steps to Reproduce:
Known upstream bug with GCC 9.x and later.




Upstream has the patch

I'm the proxied maintainer for this package, so you can assign the ticket to me.

I already have the patches for this from upstream.

Fixed in icon-9.5.20h which is now in portage
