Dear community,

it seems that commit 32803 produces invalid binaries for ARM CPUs.
I`ve tried to compile applications for Windows CE and then also for
Raspberry Pi 2, but after this commit no application is able to run
and always ends with segmentation fault.

Here is bug report: http://bugs.freepascal.org/view.php?id=29305

GDB backtrace showed this on Raspberry Pi 2:
Code: [Select]0x00013300 in fpc_initializeunits ()
(gdb) bt
#0  0x00013300 in fpc_initializeunits ()
#1  0x00013308 in fpc_initializeunits ()
#2  0x00013308 in fpc_initializeunits ()
#3  0x00013308 in fpc_initializeunits ()

Can anybody give some hints/directions where to look at when debugging
this kind of problem?
Any pointers where to look on?

Start with reading "svn diff" documentation

Thanks for help, but I already did that (see bug report from 1st
post).
Now the question is why fpc_initializeunits fails while calling
fpc_cpuinit on ARM
