Bug ID: 106482
Summary: [12 Regression] bootstrap of 12.1.0 using 4.8.2 fails
with C++ errors
Product: gcc
Version: 12.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: skunk at iskunk dot org
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: x86_64-pc-linux-gnu
Build: x86_64-pc-linux-gnu
I attempted to bootstrap 12.1.0 using GCC 4.8.2. The documented prerequisites
include an "ISO C++11 compiler," so this appears to be a supported arrangement.
GCC 12 was configured with --disable-shared --disable-nls
--enable-version-specific-runtime-libs --with-pic --disable-multilib
--with-arch=opteron --disable-libcc1 --enable-languages=c,c++,lto
The bootstrap failed as shown below. I was able to bootstrap 10.2.0 using the
original compiler, and then bootstrapped 12.1.0 with that intermediary.
