1. modify crash.spec and build cp %{SOURCE1} . -make RPMPKG="%{version}-%{release}" CFLAGS="%{optflags}" CXXFLAGS="%{optflags}" LDFLAGS="%{build_ldflags}" +make RPMPKG=8.0.0-5.el9 'CFLAGS=-O2 ... # rpmbuild -ba crash.spec 2. reproduce # BUILD/crash-8.0.0/crash ... crash> p /usr/include/c++/11/string_view:234:... 3. modify crash.spec and build with the patch +Patch7: gdb-assert.patch +%patch7 -p1 # rpmbuild -ba crash.spec 4. cannot reproduce # BUILD/crash-8.0.0.fix/crash ... crash> p Display all 174031 possibilities?
