according to Tom's reply it is a regression by:

but the Ada testcase does not work for me (it always PASSes for i386 and it
always FAILs for x86_64).  Do you have some precompiled binaries so that I can
look at them.

I will then code a gdb.dwarf2/ testcase as the gdb.ada/ testcases are IMO
dependent on too many factors and in Fedora environment they are not reliable.


Thanks,
Jan
