What we get is a bizarre error which gives little information as to why it barfs
Compilation works perfectly if using snapshots from may. That is what I have on my funtoo odroid right now.

Here are the last messages of the compilation of the latest snapshots as of Sept 2nd. The result has been identical since may. Someone introduced a deadly bug that kills compilation on ARM devices. This was done on an Odroid U2.

The last successfull compile I had was using a fpc.zip  that my funtoo had in a cache. So I think that the last non broken fpc was around the 15th of may or slightly before that. It would be nice to have better error message that just an Access violation.
There is no way to figure out what happen when the error comes from the OS. Can't the compiler traps this kind of stuff and get us more informative clue as to what happened?
The crash seems to be caused by the UnicodeString stuff, if that is the case why the Warning instead of an error?
