GCC Bugzilla Bug 7015

finish_asm_stmt, in its output_operands loop, sets 'operand'
to the same value for all output operands, thus causing
problems with the mark_addressable call at the bottom of the
loop.

Release:
3.1

Environment:
Cross compilers running on Cygwin (Win2K).

How-To-Repeat:
The problem is obvious, and I don't have a specific example
at hand.

Fix:
Replace

operand = TREE_VALUE (output_operands);

with

operand = TREE_VALUE (t);

State-Changed-From-To: open->feedback
State-Changed-Why: although obvious, could you provide a test case that I 
    can insert in the testsuite

Responsible-Changed-From-To: unassigned->nathan
Responsible-Changed-Why: patching

State-Changed-From-To: feedback->analyzed
State-Changed-Why: test case received
