SYSRIVECT and MSP430F534x and suspect stack overlap

Dear All

I'm using a board whit MSP430F534x and I would use the interrupt vector 
RAM mapping via SYSRIVECT.

Seems correct my assigment of address of interrupt procedure in the ram 
(top of ram) , according different examples, but when I launch 
application the debug goes in crash after __enable_interrupt() and I 
suspect that stack RAM use top RAM (as remapped vector) and in fact.

If is true my suspect of stack/heap corruption, I suppose is necessary 
to modify the ld file

Can someone else help me regarding ld file, to define in correct way 
stack limit and reserved ram for SYSRIVECT action ?

Thanks , Daniele
