Bug ID: 83756 Summary: gcc (mingw64) 7.2.0 ICE on boost::call_once Product: gcc Version: 7.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: jacobgodserv at gmail dot com Target Milestone: --- Created attachment 43076 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43076&action=edit Original sanitized output - The exact version of GCC: x86_64-5.4.0-release-win32-seh-rt_v5-rev0. I was able to reproduce also on 4.9.4 and 7.2.0 equivalents but I forgot to write the exact versions. I tried to keep the toolchains as equal as possible except for versions. I can get exact names if you guys need them. The maintainer of mingw64 said they could also reproduce on 7.2.1, and said it's a vanilla gcc bug which is why it's here. - The system type: Windows 7 64-bit, Intel - The options given when GCC was configured/built: This is a mingw-w64-distributed build: Configured with: ../../../src/gcc-5.4.0/configure --host=x86_64-w64-mingw32 --build=x86_64-w64-mingw32 --target=x86_64-w64-mingw32 --prefix=/mingw64 --with-sysroot=/c/mingw540/x86_64-540-win32-seh-rt_v5-rev0/mingw64 --with-gxx-include-dir=/mingw64/x86_64-w64-mingw32/include/c++ --enable-shared --enable-static --disable-multilib --enable-languages=c,c++,fortran,lto --enable-libstdcxx-time=yes --enable-threads=win32 --enable-libgomp --enable-libatomic --enable-lto --enable-graphite --enable-checking=release --enable-fully-dynamic-string --enable-version-specific-runtime-libs --disable-isl-version-check --disable-libstdcxx-pch --disable-libstdcxx-debug --enable-bootstrap --disable-rpath --disable-win32-registry --disable-nls --disable-werror --disable-symvers --with-gnu-as --with-gnu-ld --with-arch=nocona --with-tune=core2 --with-libiconv --with-system-zlib --with-gmp=/c/mingw540/prerequisites/x86_64-w64-mingw32-static --with-mpfr=/c/mingw540/prerequisites/x86_64-w64-mingw32-static --with-mpc=/c/mingw540/prerequisites/x86_64-w64-mingw32-static --with-isl=/c/mingw540/prerequisites/x86_64-w64-mingw32-static --with-pkgversion='x86_64-win32-seh-rev0, Built by MinGW-W64 project' --with-bugurl=http://sourceforge.net/projects/mingw-w64 CFLAGS='-O2 -pipe -I/c/mingw540/x86_64-540-win32-seh-rt_v5-rev0/mingw64/opt/include -I/c/mingw540/prerequisites/x86_64-zlib-static/include -I/c/mingw540/prerequisites/x86_64-w64-mingw32-static/include' CXXFLAGS='-O2 -pipe -I/c/mingw540/x86_64-540-win32-seh-rt_v5-rev0/mingw64/opt/include -I/c/mingw540/prerequisites/x86_64-zlib-static/include -I/c/mingw540/prerequisites/x86_64-w64-mingw32-static/include' CPPFLAGS= LDFLAGS='-pipe -L/c/mingw540/x86_64-540-win32-seh-rt_v5-rev0/mingw64/opt/lib -L/c/mingw540/prerequisites/x86_64-zlib-static/lib -L/c/mingw540/prerequisites/x86_64-w64-mingw32-static/lib ' - The complete command line that triggers the bug: Really barely anything.
