Source: rustc
Version: 1.31.0+dfsg1-2
Severity: normal
Tags: upstream
User: debian-sparc at lists.debian.org
Usertags: sparc64


The build of rustc fails on sparc64 due to a compiler regression with multiple
bus errors meaning that an unaligned access has occurred [1].

The upstream commit which introduced the regression can be found in [2]. It can
simply be reverted for 1.31.0 to fix the problem. I have reported the issue
upstream as [3].
