// The call sequence is as follows:
|
|
//
|
|
// js -js2wasm-> i1.callAnother()
|
|
// -wasm2wasm-> i0.callAnother()
|
|
// -wasm2js-> i1.boom()
|
|
// -calldirect-> i1.doStackCheck()
|
|
// -calldirect-> dummy()
|
|
// -calldirect-> i1.doStackCheck()
|
|
// -calldirect-> dummy()
|
|
//
|
|
// We therefore have i1 indirectly calling into itself, through another
|
|
// instance. When returning its cached stack limit should still be valid, but
|
|
// our implementation used to set it to UINTPTR_MAX causing an erroneous stack
|
|
// check failure at the second doStackCheck() call.
