You might try removing -fprefetch-loop-arrays which seems to be a finicky optimization flag in many situations. My experience with the varied stability of optimization flags beyond what is added via -O3 leads me to believe that this is your culprit. I've been wrong before. I'll be wrong again.
Sorry, Nick, you were wrong. I ran 'emerge audacity' again today. id3lib built without incident. I did not change any compiler flags. audacity failed to build. Gave me hint: set USE=-gtk2. I tried that, and it failed with a seg fault. I tried it again and it built successfully. I have seen similar behavior with other package builds. Looks like this version of gcc is flaky (version 3.2.3 20030422).
that version of gcc (among other 3.x gcc releases) is flaky with some of the extended optimization flags as I said previously... Nothing is really fixed... nothing has changed... so i'm not wrong yet. :) I am going to change this bug to INVALID as there are no problems with id3lib.
