           Summary: pipe hang when program compiled with -maix64 and -static
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: kminola@eng.umd.edu
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: powerpc-ibm-aix5.2.0.0
  GCC host triplet: powerpc-ibm-aix5.2.0.0

% 

the following bug was observed.

% gcc -o foo foo.c -maix64 -static
% echo 10 | foo    <- hangs!!!

Both -maix64 and -static as arguments seem to be necessary
to demonstrate the bug.

Using the native cc compiler and similar arguments, there
is no bug:

% cc -o foo foo.c -bstatic -q64 -bI:/lib/syscalls.exp
% echo 10 | foo
% 

The bug also occurs using gcc-20030616 (the latest development
snapshot).
