Summary

0000079: Assertion fail in second run

Description

I am trying to debug the error it appeared in INET Quagga days before and others that appear in my own networks supposedly by a misconfiguration, but it does not appear any debug information in quagga code:

Is necesary to do any special to the build configuration in INET Quagga to get the debug information in quagga? I have the whole project with gcc-debug...

Additional Information

The error appears when is executed line 179 of table.c (in lib directory):

assert (prefixlen <= 128);

And prefixlen value is "-127".

This value is get from a "route table" obtained with this method:

/* Lookup route table. */
struct route_table *
vrf_table (afi_t afi, safi_t safi, u_int32_t id)
{
  struct vrf *vrf;

  vrf = vrf_lookup (id);
  if (! vrf)
    return NULL;

  return vrf->table[afi][safi];
}
