The arch is ubicom, which is not mainlined, however I see a similar/same problem when following vfork() on ARM-nommu: it gets stuck as soon as the child does vfork(). Then again, I use a patched strace-4.5.12 to get it to work on ARM-nommu, since the original uses fork() to start the child process. And the device I'm using it on has a very ancient kernel, 2.4.26-uc0, which doesn't qualify as relevant :-) The ubicom folks, on the other hand, are following 2.6 closely. David, are you able to confirm that any other NOMMU architecture and current strace is able to follow a child which does vfork()? -- Jamie _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
