From a741ef9611e4ed9111a2e18f8f10d9a3ffa19f90 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 9 Jul 2026 16:49:36 +0000 Subject: [PATCH] diff: widen `deflate_it()`'s bound local from int to `size_t` Fixes a pre-existing silent narrowing from `git_deflate_bound()`'s `unsigned long` return into an `int` local: anything past 2 GiB has always wrapped negative here and then been re-extended to `size_t` inside `xmalloc()`. Also prep for the upcoming `git_deflate_bound()` widening to `size_t`, which would extend the narrowing further if `bound` stayed `int`.
