Martin Sebor <msebor at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |msebor at gcc dot gnu.org --- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> --- Note that an uninitialized local variable has an indeterminate value which, even if it's not a trap representation, can appear to change from one instance to another, and whose use results in undefined behavior (see also https://gcc.gnu.org/ml/gcc/2019-01/msg00199.html).
