So I owe this thread a bit more input. Randy, you're completely right. And especially the compile task in question, "gcc -o insn-attrtab.o" (shortened), is rather CPU- but not kernel-intensive. I don't know what exactly it does (not familiar with gcc internals), but it _heavily_ depends on the optimization level. So my suggestion to the OP would be to carefully look at the CFLAGS. Maybe -- please correct me if that is the case -- is a gcc build restricted to certain CFLAGS, though. At this stage, I would exclude a race condition involving the kernel, e.g. some stale or missing files. It may have to do with threading, but gcc doesn't thread. Question to the OP: What is the larger context of that gcc build? A simple update? A larger scale configuration change? -hwh -- gentoo-user@gentoo.org mailing list
