In 2.6.18.1, clear_single_step is defined as an inlined call in arch/powerpc/kernel/ptrace.c (ppc64) or arch/powerpc/kernel/ptrace.c (ppc32). Although it is also defined as macro in arch/powerpc/kernel/traps.c, I think ptrace_disable is using its inlined call definition. > > I'm going to need preprocessed sources, a compilation command line and > a compiler version number in order to try to get more detailed info > and fix the compiler bug, if there is one. > > Ideally, such info should be in a Systemtap bug report at > sources.redhat.com or bugzilla.redhat.com. > Thanks. I've opened bug 3441 for this and attached some data. http://sourceware.org/bugzilla/show_bug.cgi?id=3441 Please let me know if more info is needed. -Guijian
