Hello, It's been a while since last time I was able to compile the GCC mainline under cygwin (no crosscompiler). For a long period, I got an ICE very early in stage1, today I tried again, and it actually goes a lot furhter, but eventually crashes while compiling libstdc++. I get this:

See <URL:http://gcc.gnu.org/bugs.html> for instructions. I have updated the whole cygwin environment just today (all stable packages), I'm using gcc 3.2 to bootstrap: Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/3.2/specs Configured with: /netrel/src/gcc-3.2-3/configure --enable-languages=c,c++,f77,ja va --enable-libgcj --enable-threads=posix --with-system-zlib --enable-nls -- with out-included-gettext --enable-interpreter --disable-sjlj-exceptions --disabl e-ve rsion-specific-runtime-libs --enable-shared --build=i686-pc-linux --host=i68 6-pc -cygwin --target=i686-pc-cygwin --enable-haifa --prefix=/usr --exec-prefix=/ usr --sysconfdir=/etc --libdir=/usr/lib --includedir=/nonexistent/include --libe xecd ir=/usr/sbin Thread model: posix gcc version 3.2 20020927 (prerelease) Is this a known problem? Is there a workaround? I would like to file a proper bug report to GNATS, once we identified correctly the problem. BTW GCC 3.3 branch was also broken (same ICE in stage 1) last time I tried, I will try again today.
