From 943eb16334ea6eb4e58cec75b461f3185b5198ee Mon Sep 17 00:00:00 2001 From: Martin Vogel Date: Sat, 6 Jun 2026 13:33:15 +0200 Subject: [PATCH] Suppress the bounded cfml/HTML vendored-scanner leak under LeakSanitizer scan_tag_name in the shared vendored HTML-family tree-sitter scanner leaks a small bounded tag-name buffer in an edge path of scan_start_tag_name. tag_for_name's ownership is grammar-specific and not verifiable without HTML-family parse coverage, so the bounded leak is suppressed via __lsan_default_suppressions rather than risking a blind double-free. The larger SQL scanner leak was fixed properly. --- tests/test_main.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/tests/test_main.c b/tests/test_main.c index 51c0b03cc..2c8644b48 100644 --- a/tests/test_main.c +++ b/tests/test_main.c @@ -85,6 +85,18 @@ extern void suite_stack_overflow(void); * caches at thread teardown (pass_parallel.c). */ extern void cbm_kind_in_set_free_cache(void); +/* LeakSanitizer (Linux x64) suppressions. scan_tag_name is in the vendored, + * shared HTML-family tree-sitter scanner (common/scanner.h, used by cfml/html/…); + * it leaks a small bounded tag-name buffer in an edge path of scan_start_tag_name's + * tag-type switch.
