Hi Andreas,

I am debugging under qemu, and I can debug easily just to a moment 
before relocation.
If I reload symbols to my relocation address qemu does not stop at 
breakpoints (after I reinserted them).
As I understand qemus list there is a problem with relocated code. 
Anyway, you're right I'll ask.
Regarding my problem, debugging with prints showed me that it fails when 
malloc tries to extend top area,
and the top pointer seem to be in SDRAM.
If I do not use malloc before relocation (with enabled malloc_f) all 
seems to work just fine.

Regards,
Marcin
