I've seen that too, but only at the end of bisection, when it tries to
display the bad commit.

For example, when running git bisect on git://gcc.gnu.org/git/gcc:

$ git bisect start de4fa746271d39d490b59bdfbbdd2cf5b54c0521 dd58bf212e9a250300e64d78748418b01d0035cd
Bisecting: 0 revisions left to test after this (roughly 0 steps)
[f529d395184700e2404f4a293a2198355ab7ded5] Daily bump.
$ git bisect good
de4fa746271d39d490b59bdfbbdd2cf5b54c0521 is the first bad commit
commit de4fa746271d39d490b59bdfbbdd2cf5b54c0521
fatal: you want to use way too much memory
