From 28663310a6a7f2459e3af633a3b1528d22b9ac06 Mon Sep 17 00:00:00 2001 From: Shixin Wang Date: Tue, 16 Dec 2025 13:41:08 +0800 Subject: [PATCH] Fix memory leak in tzparser.c When overriding a timezone entry in addToArray(), original midptr->zone string was leaked before being replaced with the new entry->zone. Add pfree() call to free the old zone string before overwriting it.
