Using gdb:
GNU gdb 4.17.0.14 with Linux support
Copyright 1998 Free Software Foundation, Inc.
GDB is free software, covered by the GNU General Public License, and you

This GDB was configured as "i386-redhat-linux".
If you run gdb on main, and step through the program, you will see that
when gdb loads symbols for foo2.so, it does not update the internal
symbol
table for the symbol foo().
If you step into the newly loaded foo() function pointer and try a
backtrace,
you get something like the following:
#0 0x400155b0 in __do_global_ctors_aux ()
#1 0x804854f in main () at main.c:17
#2 0x40033cb3 in __libc_start_main (main=0x80484c8 <main>, argc=1,
argv=0xbffffb24, init=0x8048354 <_init>, fini=0x80485ec <_fini>,
rtld_fini=0x4000a350 <_dl_fini>, stack_end=0xbffffb1c)
at ../sysdeps/generic/libc-start.c:78
I will be working on this today, but if you have a fix, or know where to
look, any help would be appreciated.
Thanks!
