746150 - Assertion failure: [infer failure] Missing type pushed 0: void, at js/src/jsinfer.cpp:352

Status: RESOLVED DUPLICATE of bug 747926

(Core :: JavaScript Engine, defect)

Description

[Christian Holler (:decoder)]

The following test asserts on mozilla-central revision c61e7c3a232a (options -m -n):


gczeal(2);
exhaustiveSpliceTestWithArgs();
function exhaustiveSpliceTestWithArgs() {
    var errorMessage;
    var reason = "";
    for (var first = 2;;) {
        actualSpliced = []
        actualSpliced.push(schedulegc(""));
        reason = reason + errorMessage
    }
}


This could be a problem with the type taken/returned by the shell-only function "schedulegc", but it could also be some other problem. Marking s-s because infer failures can be critical and test involves gczeal.

guessing at severity based on previous inference failures

autoBisect shows this is probably related to the following changeset:
