[Openmcl-devel] compiler bug on AMD64 (problem in error printing?)

A bug found using Paul Dietz's ansi-test suite, run in compiled mode.
The optimize declaration is necessary to provoke the segfault.


Welcome to OpenMCL Version 1.1-pre-060705 (Beta: LinuxX8664)!
? (compile nil (lambda () (declare (optimize (safety 3))) (cadr 'a)))
