I can easily reproduce your segfault with our own mailmap, by picking at random an entry with both name and e-mail listed as the mapping source, e.g. $ git check-mailmap ksaitoh560@xxxxxxxxx > With a mailmap file containing: > > A <a@xxxxxxxxxx> B <b@xxxxxxxxxx> > > I get the following unexpected result: > > $ git check-mailmap b@xxxxxxxxxx > <b@xxxxxxxxxx> > > Based on my interpretation of the mailmap documentation, I would have > expected this to translate to "A <a@xxxxxxxxxx>". After reading "git help mailmap" twice, my interpretation is different (disclaimer: I haven't read the implementation of the mailmap code lately, and the last time I read any part of it is probably at least a few years ago if not before). Unlike "please map anybody with this e-mail address to 'A <a>'" entry, which is spelled "A <a> <b>", the "fully spelled" form limits the damage to those that match both name and e-mail, in order to avoid "D <b>" from getting modified, while rewriting "B <b>" to "A <a>". So I would not expect a request with no name to be mapped at all. And the command emits the e-mail intact when it does not find any match, "b@xxxxxxxxxx" being answered by "<b@xxxxxxxxxx>" is quite expected from my point of view. Thanks.
