Can you catch that build output in a file, so it could be reproduced by
running 'cat build.log' in eshell? I tried copying the fragment you
have in your backtrace a couple of times to make it longer, but I was
unable to trigger the error. Perhaps the particular contents of the
string matters too (some values might let the matcher short-circuit the
backtracking).
