Bug ID: 102233
Summary: Compiling a smallish binary with -fanalyzer seems to
cause very very long compile times
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: rjones at redhat dot com
Target Milestone: ---
This is not so simple to reproduce. It starts with checking out:
https://github.com/libguestfs/libguestfs
and compiling it. On Fedora, following the instructions here:
https://libguestfs.org/guestfs-building.1.html#short-cut-for-fedora-or-red-hat-enterprise-linux-rhel-users
# dnf builddep libguestfs
# dnf install autoconf automake libtool gettext-devel
$ git clone https://github.com/libguestfs/libguestfs
$ git submodule update --init
$ autoreconf -i
$ ./configure CFLAGS=-fPIC
$ make
The thing which fails to compile is a unit test in lib/:
$ make -C lib clean
$ make -C lib
$ make -C lib unit-tests CFLAGS="-O2 -g -fanalyzer" V=1
For me this takes a very long time linking the unit-tests binary:
