I ran a back trace.

(gdb) bt
#0  0x00000000 in ?? ()
#1  0x2862ef0c in __do_global_dtors_aux () from /usr/local/lib/libmpcdec.so.4

#9  0x08070d2a in lt_dlexit ()
#10 0x08059388 in decoder_cleanup ()
#11 0x080533b0 in main ()

Although no debugging symbols in the binary, it shows that there's
something wrong with the libmpcdec.  Hope it helps.
