__gxx_personality_v0 (PERSONALITY_FUNCTION) begins with:

__cxx_exception *xh = __get_exception_header_from_ue (ue_header);

The function __get_exception_header_from_ue() is defined in
unwind-cxx.h at line 156.

eh_personality.s debugging information states:

LCFI..32:
.bi "/usr/gnu/src/gcc-3.0/libstdc++-v3/libsupc++/unwind-cxx.h"
.line 19
addi 28,7,-48
.ei "/usr/gnu/src/gcc-3.0/libstdc++-v3/libsupc++/unwind-cxx.h"
.line 1
stw 0,8(1)
.line 18
addi 0,7,24
.line 1

Line 19 of unwind-cxx.h is
// Boston, MA 02111-1307, USA.

which is exactly the line displayed when stepping through
that part of the function in a debugger, but not the correct
line 156.
