Description of problem:
gdb does not allow to debug a simple program (helloworld.c). It stops with
a SIGTRAP, presumably in ld-linux.so and on 'cont' drops me into a sub
shell. Returning with exit to gdb, I find my program 'finished' (according
to gdb) but I cannot examine it.

Ignoring SIGTRAP in gdb ('handle SIGTRAP nopass') simply terminates my
program.

gdb behaves properly on a variety of systems with glibc 2.1.3 (instead of
2.2.4-19 as on this system).

How reproducible:
Always

Steps to Reproduce:
1.cat >hoo.c <<EOF
#include <strings.h>
int main () { printf("Hello Universe!\n");  return 0; };
EOF
2. gcc -o hoo hoo.c
3. gdb hoo
4. [gdb] run
Additionally, check dynamic linking:
   ldd ./hoo
Program works:
   hoo
	

Actual Results:  3. GNU gdb 5.0rh-5 Red Hat Linux 7.1
4. (gdb) run
Starting program: /sansom/kir/oliver/tmp/hw/hoo 

Program received signal SIGTRAP, Trace/breakpoint trap.
0x15557e90 in ?? ()
(gdb) cont
Continuing.
oliver@homer [oliver/tmp/hw]> logout
bash: logout: not login shell: use `exit'
oliver@homer [oliver/tmp/hw]> exit
exit

Program exited normally.
(gdb) 

Linking: ldd hoo
 	libc.so.6 => /lib/i686/libc.so.6 (0x1557c000)
	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x15556000)
Program runs as expected:
Hello Universe!

Expected Results:  gdb should have run the program without getting a
SIGTRAP, printing Hello Universe!, and it should have also allowed me to
set break points and examine the program.
