Bug ID: 92442
Summary: Compiling Boost.Spirit.X3 code uses exuberant amount
of RAM
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: vanboxem.ruben at gmail dot com
Target Milestone: ---

preprocessed source for reproduction
Compiling the attached preprocessed code like this:
g++ -pedantic-errors -Wextra -Wconversion -Winit-self -Wmissing-include-dirs
-Wstrict-aliasing -Werror -ffunction-sections -fdata-sections -gsplit-dwarf -g
-fPIE -std=c++17 -MD -MT test.o test.ii
consumes a peak amount of 7227,6 MB of RAM. Subsequent assembler call uses 2283
MB of RAM.
Clang 9 uses 4941 MB of RAM, which is also quite a lot, but almost 2 GB less.
