inferGenericReturnType resolved a generic call's return-type AST ($R, !E) in the CALL-SITE module context. For a re-exported fn the error-set name (LE / IoErr, re-exported as LE :: lib.LE) resolved through the call-site alias to a TypeId NOT tagged .error_set, so the planned result was a tuple whose last field wasn't an error set — errorChannelOf saw a plain tuple and the value- failable's ! channel was lost (try/or rejected it / built a malformed i1 PHI). monomorphizeFunction already pins the source to the fn's defining module before resolving the return type; inferGenericReturnType did not, so the planned call-result type disagreed with the instance's real signature. Fix: pin the source to fd.body.source_file around the return-type resolution (binding-build stays in the call-site context — its args are typed there). Regression test examples/1058-errors-reexport-value-failable-channel.sx (+ companion lib.sx). Suite green 732/0.

// A generic value-failable fn `($R, !E)` reached through a RE-EXPORT alias
|
|
// keeps its `!` error channel at the call site — the result types as a
|
|
// value-failable, so `or` / `try` accept it. Mirrors std.sx's
|
|
// `await :: io_mod.await` (+ `IoErr :: io_mod.IoErr`) re-export.
|
|
// Regression (issue 0153): the planned call-result type was resolved in the
|
|
// CALL-SITE module (where `LE` is a re-export alias → a non-`.error_set`
|
|
// TypeId), so `errorChannelOf` saw a plain tuple and `b.get() or {…}` built a
|
|
// malformed i1 PHI. The fix pins return-type resolution to the fn's defining
|
|
// module, matching `monomorphizeFunction`. Needs BOTH generic + re-export.
