This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig60F5FE3FC270CAA1F739EC28 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable On 10/14/11 17:25, Eric McCorkle wrote: > I've seen the same behavior with a clang build.=20 Actually, no. I looked into it more, and what I found is suspicious. I had the tests failing in Magick++/attributes.sh. What's suspicious is it would claim to have a random, and often nonsensible number of failures (-21563, or something). I opened up attributes.cpp, expecting to find an uninitialized variable, however, there is an "int failures =3D= 0" at the top of the main function. After a while, I moved the declaration outside of the main function, and the test worked. This tells me it's getting corrupted somehow, perhaps by a buffer overflow of some kind. Has anyone else seen this? --------------enig60F5FE3FC270CAA1F739EC28 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iQIcBAEBAgAGBQJOmM/BAAoJENSCzbQ+koZ7/YYQAJS8tvb8PT4BmY8w5pt+t367 gVzr8JfmnqXtOiCVJceSmMbpROrc87SiPA5QjO73Yy97JG7FojAgPcHPWgQUb2Am evM17t2Lz36RfpEKQupXB1mGYR+I/Gtbf/pIPLgptZqyCufVWWhCDS5d/Q6d7qK9 uWFeiLibhB0T0X3hX7Oik1bKjMI11ViYI4JIqVKCAkEq59Nnx14Iyd+zZIrdgYed gXoGp4DtZsF/qzfkXl8mT6gzImtVSRWd9aiEebIX6cVc1Cgu9+igAKc+lrBGJhfG IOLen6lC3k702Y8H4SXRwzFJvvOpKw0Z7Ktpy61Q6zQ8fS1YNiTPcQuhAhrzGrWY FQ+maRfAbT2CD0MT7q/PVn/6w6d2fvQW0RCboQNqBnbo+DNJ6s+/eumZ+a0IyI3m 9sfeVn8/thPqbm9o8SPTVBzFIPc5H82Xrts4tuG9w4NJGfVYHZ3cohSLydjVzZb7 v9UMeB1DWTpDU0VENlCwBXrIIIjlGWLaOBCqDtjrX6l+9P88YEHaEKEOA6A9nKWL YUqLLsAVvcx3fSW4vyDe4ec5LFysAgQgJ59SkXSR0aoB/11g0PJErF6Cu8i+roig SKZBQTBHs7pos/PnRiZW237gq0RjCUoi+z8HMz3Sae70EAW09utDlrQCO5EdekxN RKZg/94r3jBZ6DmdL3J0 =LjLX -----END PGP SIGNATURE----- --------------enig60F5FE3FC270CAA1F739EC28--
