From 580cf0f2f6d38221fc4c5f17155c311915301a5c Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 26 Sep 2025 10:32:51 +0000 Subject: [PATCH] imap-send: be more careful when casting to `curl_off_t` When casting a `size_t` to `curl_off_t`, there is a currently uncommon chance that the value can be cut off (`curl_off_t` is expected to be a signed 64-bit data type).
