Crash on Android
Now I tried to run it on Android (386), but it crashes:

If I disable it there as well, ... it works ? (currently I am not able to run my tests on Android)
These things are why I do not trust handwritten assembler
Which compiler? FreePascal or the NextGen Android/iOS Compiler? And which version?
It still happens with new fpc (and disabling the assembly blocks fixes ti)
