Status: RESOLVED DUPLICATE of bug 1394492

(Core :: JavaScript Engine, defect)

Description

[Christian Holler (:decoder)]

The following testcase crashes on mozilla-central revision b911a4c97fde (build with --enable-posix-nspr-emulation --enable-valgrind --enable-gczeal --disable-tests --enable-stdcxx-compat --disable-profiling --enable-debug --enable-optimize, run with --fuzzing-safe --ion-offthread-compile=off):

let moduleRepo = {};
setModuleResolveHook(function(module, specifier) {
    throw setModuleResolveHook++;
});
let c = moduleRepo['c'] = parseModule("export * from 'a'; export * from 'b';");
c.declarationInstantiation();
