Well, fiddling with BOOT_CFLAGS is at your own risks, LTO bootstrap works if
you use the right procedure: configure --with-build-config=bootstrap-lto and
type 'make'. I suspect that the problem comes from the -O3 option. That being
said, LTO indeed generates patterns that easily confuse the DWARF back-end.
However, I cannot reproduce and this is expected: the reported error can only
occur if -g is used during the bootstrap and your script doesn't have it...
And ADA is the American with Disabilities Act; the programming language is
called Ada, this is the first name of Lady Ada, Countless of Lovelace.
