I'm having an issue with klibc on sparc64 (i.e. a 64-bit userspace binary), which doesn't appear on sparc32: If I leave the signal restorer function as NULL, I get a SIGSEGV on attempting to return from the signal handler. If I generate a system call stub for rt_sigreturn, and pass that in as the restorer, then the process will loop forever on signal handler return. A lot of architectures have ugly corners in this area (i386, for example, needs to drop one word from the stack before calling the sigreturn system call.) However, I simply don't understand the SPARC architecture well enough to understand if/what I'm supposed to do here, or if this is simply a bug. -hpa - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
