Can anyone lend assistance in debugging the Sun regressions for Boost Preprocessor? The early access edition of the Studio 9 compiler is failing on BOOST_PP code that compiles just fine under earlier versions. The code that's failing appears to relate to the expansion (or lack thereof) of the macros that implement BOOST_PP_WHILE. I'm continuing to investigate, but since I'm unfamiliar with what the macros are *supposed* to do, I'm hoping someone can spot the trouble more quickly than I can. I've attached the preprocessed code from libs/preprocessor/test/control.cpp. Thanks in advance, Christopher -- Christopher Currie <codemonkey@gmail.com> #1 "/home/ccurrie/src/boost/libs/preprocessor/test/control.cpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/arithmetic/add.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/arithmetic/dec.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/config/config.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/arithmetic/inc.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/while.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/cat.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/debug/error.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/detail/auto_rec.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/iif.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/list/fold_left.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/while.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/list/detail/fold_left.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/expr_iif.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/list/adt.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/detail/is_binary.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/detail/check.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/logical/compl.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/tuple/eat.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/list/fold_right.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/while.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/list/detail/fold_right.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/list/reverse.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/logical/bitand.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/detail/while.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/logical/bool.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/tuple/elem.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/deduce_d.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/expr_if.hpp" #1 "/home/ccurrie/src/boost/boost/preprocessor/control/if.hpp" #1 "/home/ccurrie/src/boost/libs/preprocessor/test/test.h" #1 "/opt/SUNWspro/prod/include/CC/std/cstdio" #1 "/usr/include/sys/feature_tests.h" #13 "/usr/include/sys/feature_tests.h" #pragma ident "@(#)feature_tests.h 1.18 99/07/26 SMI" #1 "/usr/include/sys/isa_defs.h" #9 "/usr/include/sys/isa_defs.h" #pragma ident "@(#)isa_defs.h 1.20 99/05/04 SMI" #158 extern "C" { #380 } #18 "/usr/include/sys/feature_tests.h" extern "C" { #181 } #1 "/usr/include/iso/stdio_iso.h" #32 "/usr/include/iso/stdio_iso.h" #pragma ident "@(#)stdio_iso.h 1.2 99/10/25 SMI" #1 "/usr/include/sys/va_list.h" #9 "/usr/include/sys/va_list.h" #pragma ident "@(#)va_list.h 1.12 99/05/04 SMI" #22 extern "C" { typedef void * __va_list ;
