Uhm, sorry about that, pasted wrong bt.
This is the correct one:
Program received signal SIGSEGV, Segmentation fault.
0x40087f91 in __gmpn_submul_1 () from /usr/lib/libgmp.so.3
(gdb) bt
#0 0x40087f91 in __gmpn_submul_1 () from /usr/lib/libgmp.so.3
#1 0x4009b2e8 in __gmpz_cdiv_r_ui () from /usr/lib/libgmp.so.3
#2 0x4022c544 in ?? ()
#3 0x4022c71c in ?? ()
#4 0x400912ae in __gmpn_bdivmod () from /usr/lib/libgmp.so.3
#5 0x400792ca in __gmpz_divexact () from /usr/lib/libgmp.so.3
Alright, now I too see a SIGSEGV.
Unfortunately, my attempts at reproducing failed.
Please write a bug report along the lines of
