I found a strange problem, and the locale stuff is confusing me + gdb, maybe
someone has any ideas offhand what happens here...

The attached program works as expected when compiled under sparc64 -current:

[/tmp] martin@setting-sun > ./dltest 
dll open: 0x40210400
symbol: 0x404e30f0
dll closed
[/tmp] martin@setting-sun > ./dltest crash
dll open: 0x40210400
calling setlocale(LC_CTYPE, "de_DE.ISO8859-1");
locale set.
symbol: 0x404e30f0
dll closed
[/tmp] martin@setting-sun > 

When the same program is compiled on 1.5.2 and the binary then run under
current, it crashes (inside the printf call following the setlocale):

[/tmp] martin@setting-sun > ./dltest crash
dll open: 0x40210400
calling setlocale(LC_CTYPE, "de_DE.ISO8859-1");
Segmentation fault (core dumped)

Other ports don't have this problem, but since gdb is heavily confused
too I'm a bit poking in the dark which change might have caused this.

Hints appreciated,

Martin
