[LAU] strange build problem

I've set up an old single core athlon with debian 6.0.8-i386 (the final version of squeeze) in order to compile old versions of yoshimi which won't compile on the latest version of debian testing, but I've hit a really odd problem. The programs seem to compile perfectly, with no errors reported, but they won't run. As a cross-check, I tried to compile the latest yoshimi version as well as the latest version of zynaddsubfx. Again no compile errors are reported but running them fails. zynaddsubfx give an error 'illegal instruction', while yoshimi gives 'segfault' Can anyone suggest what might be the problem? -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
