Bug ID: 84450
Summary: bootstrap-lto ICE in g-dyntab.adb
Product: gcc
Version: 7.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: steven at uplinklabs dot net
Target Milestone: ---
This bug has been around for at least a few GCC versions now, but I hadn't
gotten around to reporting it.
My configure flags:
--host=x86_64-pc-linux-gnu --build=x86_64-pc-linux-gnu
--target=x86_64-pc-linux-gnu \
--prefix=/usr \
--libdir=/usr/lib \
--libexecdir=/usr/lib \
--mandir=/usr/share/man \
--infodir=/usr/share/info \
--enable-languages=c,c++,ada,fortran,go,lto,objc,obj-c++ \
--with-build-config=bootstrap-lto \
--disable-libssp \
--disable-libstdcxx-pch \
--disable-libunwind-exceptions \
--disable-werror \
--enable-__cxa_atexit \
--enable-checking=release \
--enable-clocale=gnu \
--enable-gnu-indirect-function \
--enable-gnu-unique-object \
--enable-initfini-array \
--enable-install-libiberty \
--enable-libmpx \
--enable-linker-build-id \
--enable-lto \
--enable-multilib \
--enable-plugin \
--enable-shared \
--enable-threads=posix \
--with-isl \
--with-linker-hash-style=gnu \
--with-multilib-list=m32,m64,mx32 \
--with-system-zlib
Non-bootstrap-lto builds work fine, but if I -do- try a bootstrap-lto build, I
get this:

This is built from gcc-7-branch@257786.
Any more details I can provide?
