This is odd as the same 'constructor' (from libgnunetutil) is executed from other GNUnet binaries that do not suffer from the segfault. |

Even with libgcrypt pthread initialization (which, as we are single-threaded, should not be needed), I get: (gdb) ba #0 0x0000000800760b94 in pthread_setcancelstate () from /lib/libthr.so.3 #1 0x000000080075a911 in open () from /lib/libthr.so.3 #2 0x0000000800fa520f in open_device (name=0x800fc7e3b "/dev/urandom") at rndlinux.c:64 #3 0x0000000800fa5388 in _gcry_rndlinux_gather_random (add=0x800fa2ba0 <add_randomness>, origin=RANDOM_ORIGIN_SLOWPOLL, length=120, level=1) at rndlinux.c:122 #4 0x0000000800fa3089 in read_random_source (orgin=RANDOM_ORIGIN_SLOWPOLL, length=120, level=1) at random-csprng.c:1283 #5 0x0000000800fa2d6e in random_poll () at random-csprng.c:1109 #6 0x0000000800fa29d4 in read_pool (buffer=0x8010d8194 "", length=8, level=0) at random-csprng.c:1003 #7 0x0000000800fa1ca8 in _gcry_rngcsprng_randomize (buffer=0x8010d8194, length=8, level=GCRY_WEAK_RANDOM) at random-csprng.c:551 #8 0x0000000800fa10be in do_randomize (buffer=0x8010d8194, length=8, level=GCRY_WEAK_RANDOM) at random.c:174 #9 0x0000000800fa11d3 in _gcry_randomize (buffer=0x8010d8194, length=8, level=GCRY_WEAK_RANDOM) at random.c:216 #10 0x0000000800fa32af in _gcry_rngcsprng_create_nonce (buffer=0x7fffffffe220, length=4) at random-csprng.c:1377 #11 0x0000000800fa1305 in _gcry_create_nonce (buffer=0x7fffffffe220, length=4) at random.c:271 #12 0x0000000800f2826f in gcry_create_nonce (buffer=0x7fffffffe220, length=4) at visibility.c:1286 #13 0x0000000800de6eab in GNUNET_CRYPTO_random_u32 (mode=GNUNET_CRYPTO_QUALITY_NONCE, i=4294967295) at crypto_random.c:128 #14 0x0000000800de7b96 in GNUNET_CRYPTO_random_init () at crypto_random.c:324 #15 0x0000000800e0ea87 in __do_global_ctors_aux () from /tmp/gnbuild/lib/libgnunetutil.so.6 #16 0x0000000800dcc836 in _init () from /tmp/gnbuild/lib/libgnunetutil.so.6 #17 0x00007fffffffe750 in ??

Ok, no VPN for FreeBSD for a while. That OS is just too messed up. |
