(Expected behavior) I get the output What happened instead? (Actual behavior) fatal: Out of memory, malloc failed (tried to allocate 18446744073709551266 bytes) What's different between what you expected and what actually happened? git tries to allocate an unreasonable amount of memory Anything else you want to add: I don't have 18,000 PB of memory Please review the rest of the bug report below.
