Fix NOMMU + daemonized tracer SEGV pathname[] was getting destroyed, execve of garbage pathname failing, and to top it off, the tracer's stack was also smashed and trecer segfaulted. * strace.c (exec_or_die): New function. (startup_child): Don't use pathname[] contents after vfork, make a malloced copy instead. Explain "NOMMU + -D bug" and how we work around it. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
