--- Comment #3 from Jan Lachnitt <pepalogik at seznam dot cz> 2012-03-21 12:18:59 UTC --- Thanks for testing and for the link to GFortranBinaries. I have just installed the very recent unofficial build of gfortran: Using built-in specs. COLLECT_GCC=gfortran COLLECT_LTO_WRAPPER=c:/program files/gfortran/bin/../libexec/gcc/i586-pc-mingw32 /4.8.0/lto-wrapper.exe Target: i586-pc-mingw32 Configured with: ../gcc-trunk/configure --prefix=/mingw --enable-languages=c,for tran --with-gmp=/home/brad/gfortran/dependencies --disable-werror --enable-threa ds --disable-nls --build=i586-pc-mingw32 --enable-libgomp --enable-shared --disa ble-win32-registry --with-dwarf2 --disable-sjlj-exceptions --enable-lto Thread model: win32 gcc version 4.8.0 20120319 (experimental) [trunk revision 185521] (GCC) The result is that the ICE is still there. There are just two changes. First, there are some more warnings, and second, the ICE is reported with a different line number within GCC source: tree-data-ref.c:1964.
