wasm + ios : RangeError: Out of memory

Using both following examples:

• https://doc.qt.io/qt-6/qtquickcontrols-gallery-example.html
• https://doc.qt.io/qt-6/qtquick3d-reflectionprobes-example.html

With qt 6.5.0-rc, the apps are working on safari / chrome on iOS using single_thread toolchain only.

The apps are crashing with multi_thread on ios with RangeError: Out of memory.

Apps on both versions are working ok on linux / windows / android (13).

Used following nginx config for serving files (on https-enabled node):

   add_header Cross-Origin-Opener-Policy same-origin;
   add_header Cross-Origin-Embedder-Policy require-corp;
