commit 1d2cd5ff6a8ff79b09e342a5907b29b4c340a9a5
Author: Josh Stone <jistone@redhat.com>
Date:   Wed Oct 21 09:07:14 2009 -0700

    Relax the -Wframe-larger-than check
    
    This is just a workaround for PR10821, and should be reverted when that
    bug is fixed.

commit ebaa961812e7b29eee554025a6253d676cea6ce0
Author: Josh Stone <jistone@redhat.com>
Date:   Fri Oct 16 18:32:12 2009 -0700

    Ensure that DWARF keeps loc2c to a reasonable stack depth
    
    * dwflpp.cxx (dwflpp::express_as_string): Limit stack depth to 32.

    PR10750 cont'd: Build with -Wframe-larger-than=512
    
    * buildrun.cxx (compile_pass): Add the warning to limit the frame size
      even lower than the Kbuild default (only works for gcc 4.4+).

commit 8f805d3329e985f0ea0851fa1522ab447765af27
Author: Josh Stone <jistone@redhat.com>

    PR10750: Enforce a reasonable limit on # of varargs
    
    If we leave the number of args unbounded, then an excessively-sized
    printf could cause a kernel stack overflow.  I've arbitrarily chosen 32
    as our new maximum.
    
    * translate.cxx (c_unparser::visit_print_format): Throw if >32 args.
    * testsuite/transko/varargs.stp: Assert that 33 args aren't allowed.
    * testsuite/transok/varargs.stp: Assert that 32 args are ok.
