Friday night's build went as usual on SuSE 9.1. However, last night's build produces a memcheck which eats all the memory and swap and thrashes the machine to hell, even with trivial progs (ls). Furthermore, this message appears at startup: Warning: set address range perms: large range 2147483647, a 1, v 1 and it didn't used to. Strangely, Tom's nightly builds appear OK, except "standard" (RH 7.2); not sure if that failure is related or not. I've been looking through Saturday's commits, trying to figure out how this happened. One possibility is vg_mylibc.c:1.90 (Fix minor off-by-one error), althought that doesn't seem very likely. Another one which might somehow mess with memory layout is Tom's fix to #73818 (stack rlimit stuff). I have a vague memory from writing the leak checker, that SuSE kernels behave differently, in that they will just extend the stack downwards indefinitely (or something) if you endlessly prod just below %esp, so perhaps that's related. Anyone have any ideas? J |
