Subject: [PATCH 2/2] gnu: gmp-boot: Fix t-scan test crash
Date: Wed,  4 Aug 2021 15:41:28 -0300

GMP 4.3 was released with a bug in the t-scan test which causes it to crash
with a segmentation fault. Backport fix from upstream.

* gnu/packages/commencement.scm (gmp-boot): Apply
gmp-4.3-fix-t-scan-test.patch.
* gnu/packages/patches/gmp-4.3-fix-t-scan-test.patch: New file.

Hello,

With this and the previous patch applied, gmp-boot builds successfully
on powerpc64le-linux both in master and core-updates-frozen.

It should also fix the same problem in i686-linux:
