Looking at backtrace of shlibsign.core it seems a recursive function 
call that doesn't meet the exit condition:

ore was generated by `shlibsign'.
Program terminated with signal 10, Bus error.

and in

line: 923:

  if (!vector && PR_SUCCESS != freebl_RunLoaderOnce())

but in 
/usr/obj/pkgsrc/www/firefox/work/mozilla/security/nss/lib/freebl/prng_fips1861.c
there is note:

/* Use NSPR to prevent RNG_RNGInit from being called from separate

static const PRCallOnceType pristineCallOnce;
static PRCallOnceType coRNGInit;
static PRStatus rng_init(void)

I hope that this could be usefull as investigation to fix the bug.
