commit r16-9353-gb1a7a72d8c2aab445ab14ef116e982a14e87ab3a Author: Jose E. Marchesi <[email protected]> Date: Wed Jun 24 23:57:38 2026 +0200 a68: fix comparison of pack element names in packs_ordering Entry names of packs (struct fields, union alternatives, procedure parameter list) cannot be compared purely by pointer value. This patch fixes the union alternative sorting code to not rely on this false assumption. Signed-off-by: Jose E. Marchesi <[email protected]> gcc/algol68/ChangeLog * a68-moids-sorting.cc (packs_ordering): Do not rely on pointer comparison when comparing pack element names.
