To: Junio C Hamano Cc: Git Mailing List Content-Type: text/plain; charset=UTF-8 Sender: git-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: git@vger.kernel.org We have an odd bug report in the kernel, where somebody had trouble bisecting all the way due to "git is failing with "you are trying to use to much memory"(?!)" which can't be an exact error message quote, but the closest I can find smells like the "unsigned_add_overflows()" check in the strbuf code. Very odd. See https://bugzilla.kernel.org/show_bug.cgi?id=121701 for the bug report. I'm not seeing how that could *possibly* happen, but if it indeed is that strbuf code, maybe it could print out the function name (there are two different cases) and values so give a hint about where/how this happens.. Of course, since the bug report isn't an exact quote anyway, maybe that wouldn't have helped anyway. I asked for more information. Linus
