It's no longer an issue after the linker fixes. - - - - - d57f01a4 by Matthew Pickering at 2026-03-11T15:08:40-04:00 testsuite: Add test for foreign import prim with unboxed tuple return This commit just adds a test that foreign import prim works with unboxed sums. - - - - - 23d111ce by Matthew Pickering at 2026-03-11T15:08:41-04:00 Return a valid pointer in advanceStackFrameLocationzh When there is no next stack chunk, `advanceStackFrameLocationzh` used to return NULL in the pointer-typed StackSnapshot# result slot. Even though the caller treats that case as "no next frame", the result is still materialized in a GC-visible pointer slot. If a GC observes the raw NULL there, stack decoding can crash. Fix this by ensuring the dead pointer slot contains a valid closure pointer. Also make the optional result explicit by returning an unboxed sum instead of a tuple with a separate tag.
