--- Comment #26 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The failures in comment 22 are due to r217769 and are now fixed at r217946,
likely by r217853 (no interest to check it). Note for the record that the
double spaces were due to r217518 (libsanitizer merge from upstream r221802).

Is it worth to file a PR about the too fragile regexps in the asan tests?
