>Description:
ps -e doesn't display the environment of a 32-bit process. 

test program:
cat t.c
int main() {
  printf("long int size is %i bytes long!\n", sizeof(long));
  sleep(3600);
}

gcc -m32 t.c

./a.out &

freebsd9# ps -e
PID  TT STAT TIME COMMAND
985  v0 Is   0:00.01 TERM=xterm login [pam] (login)
993  v0 S    0:00.08 USER=root LOGNAME=root HOME=/root SHELL=/bin/csh FTP_PA
1169 v0 S    0:00.00 ./a.out
 986 v1 Is+  0:00.00 USER=xterm /usr/libexec/getty Pc ttyv1

If I compile t.c without the -m32 option, the output looks file.


>How-To-Repeat:
1. compile the test program in 32-bit mode
2. run 'ps -e'
