Thanks for testing. Please bear in mind though that this is a workaround that
makes the bug less likely to happen, but it's still possible that it triggers.

Daniel, did that make any sense whatsoever to you? There is obvious difference
in the value of 'After init' 0x01000000 (working case) vs. 0x000e4004 (broken
