    Problem Summary TSD4.103 Runaway process in command "hdrdefs" when it traverses the header file signal.h and sys/wait.h trees. For example, a portion of signal.h file looks like: >> #if (__STDC__ == 0 || defined(_ABCD_ANSI_EX...
    Problem Text

    Runaway process in command "hdrdefs" when it traverses the header
    file signal.h and sys/wait.h trees.

    For example, a portion of signal.h file looks like:

    >> #if (__STDC__ == 0 || defined(_ABCD_ANSI_EXT)) && !defined(_POSIX_SOURCE)
    >> #if _ABCD
    >> #include <sys/types.h>
    >> #endif
    >> #include <sys/procset.h>
    >> extern int gsignal(int);
    >> extern void (*sigset(int, void (*)(int)))(int);
    >> ...
    >> ...
    >> #endif

    In the normal situation, if _POSIX_SOURCE is defined, then any of the
    above definitions will not be included at compile time. When "hdrdefs"
    traverses the include file tree, it goes into the outer #if finds
    "#include <sys/procset.h>" then trying to go through more include files. Since
    there are lots of files under /usr/include, signal.h.C and signal.h.D files
    grow bigger and bigger until a write error occurred (filesystem full).

    The same thing happens in sys/wait.h at:

    >> #ifdef _KERNEL
    >> ...
    >> ...
    >> ...
    >>
    >> #if !defined(_POSIX_SOURCE) && !defined(_PROC_PROCSET_H)
    >> #include <proc/procset.h> /* COMPATIBILITY */
    >> #endif /* !defined(_POSIX_SOURCE) && !defined(_PROC_PROCSET_H) */
    >>
    >> #else
    >>
    >> #include <sys/types.h> /* COMPATIBILITY */
    >> #include <sys/siginfo.h> /* COMPATIBILITY */
    >>
    >> #if !defined(_POSIX_SOURCE)
    >> #include <sys/procset.h> /* COMPATIBILITY */
    >> #endif /* !defined(_POSIX_SOURCE) */
    >>
    >> #endif /* _KERNEL */
    >>

    The make file had to be altered in POSIX.hdr/misc/signal,
    POSIX.hdr/misc/signal_X, and POSIX.hdr/misc/wait so that the other portions
    of the test could be built to completion. Otherwise, the build aborts at
    the "hdrdefs" command. So the ".C" and the ".D" are not created nor moved
    over to TESTROOT with "chmog".

    Even though not all the files are built in POSIX.hdr/misc/signal_X,
    it still passes the execution phase because none of the tests use signal.h.C
    or signal.h.D.

    Similar problems were encountered for which a waiver was granted.
    See Waiver PG3.607.

    Test Description:
    If _POSIX_SOURCE is defined and no other feature test macros are
    defined, no other symbols than those defined or reserved by POSIX.1
    are made visible; otherwise, if _XOPEN_SOURCE is defined and no other
    feature test macros except _POSIX_SOURCE, _POSIX_C_SOURCE=1 or

    reserved by the XPG are made visible.
