Description yongxiang 2021-09-12 16:14:07 UTC 
My host is host is ~amd64 with glibc, crossdev is latest snapshot (20210718).

how to reproduce:
  crossdev -t aarch64-unknown-linux-glibc
or
  crossdev -t riscv64-unknown-linux-glibc

error: /bin/bash: line 2: 31988 Segmentation fault    (core dumped) build/genmatch --gimple /tmp/portage/cross-aarch64-unknown-linux-gnu/gcc-11.2.0/work/gcc-11.2.0/gcc/match.pd > tmp-gimple-match.c

The stable version does not have this problem：
  crossdev -S -t aarch64-unknown-linux-glibc
  crossdev -S -t riscv64-unknown-linux-glibc

My gcc/binutils/glibc version :
emerge -avp sys-devel/gcc sys-devel/binutils sys-libs/glibc
[ebuild   R    ] sys-devel/binutils-2.37_p1:2.37::gentoo  USE="doc gold nls plugins (-cet) -default-gold -multitarget -static-libs -test -vanilla" 0 KiB

Turn off the "lto" use of gcc and it will work.
Comment 4 yongxiang 2021-09-15 13:54:56 UTC 
For cross-riscv64-unknow-linux-gnu, I made a stupid mistake. After closing CCACHE, everything is OK, including lto.
