--- Comment #8 from Anh Vo <anhvofrcaus at gmail dot com> 2011-11-15 01:09:00 UTC --- with snapshot gcc-4.7-20111105, there are syntax errors in adainit.c, initialize.c, seh_init.c and tracebak.c. These files are located at /gcc/ada directory which is part of Ada compiler. I fixed these errors with my own ways (mostly adding explicit conversion), the bootstrap went further and finally crashed with a bug box as originally report as shown below. Thus, implicit-zee.c may not be an issue regarding this snapshot. /c/Gcc/Build-4.7.x/./prev-gcc/xgcc -B/c/Gcc/Build-4.7.x/./prev-gcc/ -B/usr/local /i686-pc-mingw32/bin/ -L/c/Gcc/Build-4.7.x/i686-pc-mingw32/winsup/mingw -L/c/Gcc /Build-4.7.x/i686-pc-mingw32/winsup/w32api/lib -isystem /c/Gcc/gcc-4.7-20111105/ winsup/mingw/include -isystem /c/Gcc/gcc-4.7-20111105/winsup/w32api/include -B/u sr/local/i686-pc-mingw32/bin/ -B/usr/local/i686-pc-mingw32/lib/ -isystem /usr/lo cal/i686-pc-mingw32/include -isystem /usr/local/i686-pc-mingw32/sys-include - c -g -O2 -D__USE_MINGW_ACCESS -Wno-pedantic-ms-format -gnatpg -gnata -W -Wall - nostdinc -I- -I. -Iada -I../../gcc-4.7-20111105/gcc/ada -I../../gcc-4.7-20111105 /gcc/ada/gcc-interface ../../gcc-4.7-20111105/gcc/ada/a-charac.ads -o ada/a-char ac.o gnat1.exe: warning: command line option '-Wno-pedantic-ms-format' is valid for C /C++/ObjC/ObjC++ but not for Ada [enabled by default] +===========================GNAT BUG DETECTED==============================+ | 4.7.0 20111105 (experimental) (i686-pc-mingw32) Program_Error EXCEPTION_ACCESS _VIOLATION| | Error detected at system.ads:175:5 | | Please submit a bug report; see http://gcc.gnu.org/bugs.html. | | Use a subject line meaningful to you and us to track the bug. | | Include the entire contents of this bug box in the report. | | Include the exact gcc or gnatmake command that you entered. | | Also include sources listed below in gnatchop format | | (concatenated together with no headers between files). | +==========================================================================+ Please include these source files with error report Note that list may not be accurate in some cases, so please double check that the problem can still be reproduced with the set of files listed.
