There are alpha specific macros to munge with the context of a jmp_buf that use to work but no longer do. There is a simple test program at: http://people.freebsd.org/~deischen/test_jmpbuf.c that demonstrates the problem. If someone more knowledgable about the alpha can get this to work, I can fix the problem. -- Dan Eischen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
