ldso problem on zynq

[Johannes Schlatow]

Hi Sebastian,

this was actually helpful. It was catching a Region_conflict exception thrown by Allocator_avl_base::alloc_addr().
The requested address was in a very low range so that no matching block could be found.
Actually, it was LD_TEXT_ADDR, hence modifying this value in spec-hw_zynq.mk accordingly solved my problem.

Cheers
 Johannes

Thus, I'd be very glad to get a few hints from you guys. Any ideas what I need to check to narrow this down?
