problem with exception handling

[Heinrich Roder]

Why do I get a dumped core in this program. I use
the newest snapshot installed, ( test.C is attached)

gdb gives the following
Breakpoint 1 at 0x4002aba4
-- main starts --
-- f1 starts -- 
L TraceLifetime constructed for a.
-- f2 starts -- 
LL TraceLifetime constructed for c.
LD TraceLifetime destroyed for c.

Breakpoint 1, 0x4002aba4 in abort ()
(gdb) where
#0  0x4002aba4 in abort ()
#1  0x8050029 in copy_reg (reg=16, udata=0xbffff894, target_udata=0xbffff824)
#2  0x80502b1 in __throw ()
#3  0x804a304 in f1 () at /home/hro/C++/test.C:58
#4  0x804a3e9 in main () at /home/hro/C++/test.C:66
#5  0x804a02b in _start ()
