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 =
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?
