September111111111115mo agoConfirmed. ae6e292 fixes this by making patch_replace_text duplicate the incoming value before freeing the destination slot, so it is safe when value aliases *slot. The addImport/addFunction explicit-node regression coverage is included as well.

In native/zero-c/src/program_graph_patch_ops.c:

Commit ae6e292 fixed the use-after-free by reordering patch_replace_text to copy the value with z_strdup into a temporary (char *copy) BEFORE calling free(*slot), then assigning *slot = copy. This makes the function safe even when value aliases *slot (the addImport/addFunction explicit-node case), since the source buffer is still valid at copy time. The aliasing guard from the original suggestion is no longer needed.
