LTO may break the debug symbols and make GDB unusable. There is an option, that fixes the issue: to use a -g switch in link flags. Note that this slows loading of the debug symbols significantly. I suggest these options as possible approaches: 1) make the configure script include -g in LDFLAGS when --enable-optimizations and --with-lto are used 2) same as 1), but only when --with-pydebug is also used. 3) document this problem and make the user aware that this possible fix (-g in link flags) exists
