Content
Those -g switches you see there are during compile-time. For this to work, you need to enable it also during link/time: ./configure --enable-optimizations --with-lto LDFLAGS="-g" Except for py-bt, you should also try bt. With this link flag enabled, I can observe significant slowdown on my machine during the backtrace when using bt command (At least when I let the PGO do all the profiling, when compiled with the sed edit you posted here, I observe none).
