Bug ID: 121200
Summary: RAM usage ballooning (18G) for a source file
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jeanmichael.celerier at gmail dot com
Target Milestone: ---
On the course of my build I'm observing a file that takes 18.5G of RAM and an
ungodly amount of time (more than 15 minutes on a AMD ThreadRipper 7965WX) to
build with various versions of GCC-14. It wasn't an issue with GCC-13 and is
not an issue with Clang.
This can be reproduced in the following way through an ubuntu:24.04 docker
image:
apt -yqq update
apt -yqq install git cmake
git clone --recursive -j16 https://github.com/ossia/score
cd score
source ci/ubuntu.noble.deps.sh
export CC=gcc-14
export CXX=g++-14
cmake -S . -B build -GNinja -DSCORE_DEPLOYMENT_BUILD=1
-DBUILD_SHARED_LIBS=0 -DCMAKE_BUILD_TYPE=Release
-DCMAKE_EXPORT_COMPILE_COMMANDS=1 -DCMAKE_COLOR_DIAGNOSTICS=auto
cd build
ninja
