Firefox-esr applies the followings in debian/rules to avoid this issue
1. ifeq (default,$(origin CC)) ifneq (,$(filter-out bullseye bookworm,$(DIST))) CC := clang 2. ifeq (,$(findstring clang,$(CC))) LDFLAGS += -Wl,--reduce-memory-overheads endif but if we do '1' for Thunderbird as well, we need to do careful examination for the codes, so disabling LDFLAGS += -Wl,--reduce-memory-overheads will be quick fix. When debian/rules is updated like Firefox-esr in the future, please consider enable back this option. Meanwhile, the patch might be applied to not only Trixie but also SID etc. The patch will be sent over Salsa soon. thx Taro
