[cl-opengl-devel] Trace/BPT trap with cl-opengl loading

The only hurdle for me for trying out (and maybe switching) to clozure on the mac platform is that I can't seem to get the cl-opengl package loaded. I get the error: "Trace/BPT trap" when I try to load that package. (All other dependent packages like cffi, loaded successfully). I am using ccl64, version 1.5 on Darwin/MAC OS (DarwinX8664). Latest version of cl-opengl. I believe I also tried it on the 32-bit ccl. Same problem. It looks like it only compiles a few source files in the cl-opengl package before it dies. If someone can point out to me how I can trace this to provide more information on where it is crashing or maybe someone has run across this already with this particular package. Thanks, Kevin
