Well whatever the problem was, it is not happening anymore..
I really don't know what the problem is and to be honest, I don't think
anyone else on the list could tell me unless they were here to see the
problem happen and analyze it when it happens.
It may have been something I did in my code. I was building a somewhat
complicated memory management system for LADSPA plugins and the problem
started happening.
Once I fixed the code where it worked properly the problem went away.
I just did not manage to find out what exactly was causing the problem
or why.
I have no idea but I am pretty sure I did something with unitialized
memory, and than later fixed it without realizing it . I am pretty sure
I it was a pointer problem.
I can not run gdb on my program, it won't work. The code is too hard to
debug by just looking at it. The only way I can debug is to put hundreds
of printf() into the code. That was how I found log( blah ) was making
NAN as well. I have learned to live without a debugger, but it sucks,
because I really need it.
