Description of problem:
portmap segfaults on startup in the svc_run() routine

Version-Release number of selected component (if applicable):
glibc-2.5.90-8

How reproducible:
Always

Steps to Reproduce:
1. ensure that portmap is installed
2. run '/sbin/portmap -d'
3. watch it segfault
  
Actual results:
Segfault when attempting to run

Expected results:
portmap should run without a segfault

Additional info:
Traceback in gdb shows segfault in svc_run.c:81. Looks like my_pollfd wasn't set
after initial realloc(). Rebuilding now to check if attached patch fixes problem.
