From ce15f9eb9eb9e7ac3d5095b19cd7b8c7c5bfc22b Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Wed, 14 Aug 2024 08:51:55 +0200 Subject: [PATCH] git: fix leaking system paths Git has some flags to make it output system paths as they have been compiled into Git. This is done by calling `system_path()`, which returns an allocated string. This string isn't ever free'd though, creating a memory leak. Plug those leaks. While they are surfaced by t0211, there are more memory leaks looming exposed by that test suite and it thus does not yet pass with the memory leak checker enabled.
