I found out that line builtin/blame.c:1675 makes the problems:
if (len) {
printf("blame.c:1676, subject: %s, len: %i\n", subject, len);
--> strbuf_add(&ret->summary, subject, len); <--
} else
strbuf_addf(&ret->summary, "(%s)", sha1_to_hex(commit->object.sha1));
commenting it out and compiling does not lead to crashing git
anymore. You can find below the output of printf.
git clone git://git.cyrusimap.org/cyrus-imapd
git annotate timsieved/parser.c

There is a bit of suspicious code in builtin/blame.c where it is
destroying the commit_info without ever initializing it, and this
happens many times when blaming 'timsieved/parser.c'. Does the
following patch fix the problem for you?
