In principle the ARM AROS freepascal works very nicely, but some of the LCL programs does crash, especially EdiSyn and Mapparium have this problem. I try to debug it, its strange that it only appears on ARM (i386, PowerPC, m68k no problem at this point). It seems that it is a classical use after free, but the source seems to be right. I need to check if this also happen on the other platforms and only work by random. Or ARM has special properties which bring this error. With some tricks I come around this problem and got EdiSyn and Mapparium to work. Both work well on RasPi AROS but still crash on exit so I guess there are more problems inside.
