--- Comment #18 from Óscar Fuentes <gcc_bugzilla at axeitado dot com> --- Adding --enable-frame-pointer makes no difference. No change either adding --enable-large-address-aware --with-fpmath=sse --disable-sjlj-exceptions --enable-frame-pointer --disable-libada --enable-libstdcxx Another data point: for the test mentioned on Comment 16, if I replace libstdc++.dll with the same file from gcc 10, the test works.
