On a Solaris x86_64 machine:
tempest-solaris% uname -a
SunOS tempest-solaris 5.10 Generic_141445-09 i86pc i386 i86pc Solaris
with a gdb 7.1 configured thusly:
./configure --build=x86_64-pc-solaris2.10 --host=x86_64-pc-solaris2.10
--target=x86_64-pc-solaris2.10
--prefix=/net/tools/gnu/gdb/7.1/i686_SunOS_64.5.10
--with-mpfr=/net/tools/mpfr/2.4.1/i686_SunOS_64.5.10
--with-gmp=/net/tools/gmp/4.3.1/i686_SunOS_64.5.10

--with-tk=/net/tools/tcl/8.6b1/i686_SunOS_64.5.10/lib --with-expat
--with-libexpat-prefix=/net/tools/expat/2.0.1/i686_SunOS_64.5.10
--with-curses --with-python=no --enable-tui --enable-64bit

--with-libiconv-prefix=/net/tools/libiconv/1.13.1/i686_SunOS_64.5.10
--with-libintl-prefix=/net/tools/gnu/gettext/0.17/i686_SunOS_64.5.10
--enable-targets=i686-pc-solaris2.10,x86_64-pc-solaris2.10
and built using gcc 4.3.4 configured for i686-pc-solaris2.10 (which
generates functioning amd64 binaries when I build with -m64), I can get
a reasonable stack trace from the core dump from a simple program
("hello, world" + core dump):

but I've been unable to get a sensible stack trace out of a core dump
from a more complex program:
