https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221288 Bug ID: 221288 Summary: gcc5 links against libsupc++ when compiling Product: Ports & Packages Version: Latest Hardware: i386 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: rm@gnu.org I get this stacktrace using a program compiled with gcc 5.4.0 from ports. I= t is gcc5-5.4.0_3 GNU Compiler Collection 5 but previous package versions of 5.4 had the same issue. I cannot try out h= ow 6.4 fares, because it fails to compile gnustep stuff for me. #0 0x00000000 in ??

On FreeBSD, this function should be provided by libcxxrt, not libsupc++. Please file a bug report with the FreeBSD gcc maintainer - it looks as if you=E2=80=99ve somehow ended up with a program = linking both libc++ from base and libstdc++ from ports, and the libstdc++ from ports is incorrectly using its own internal libsupc++ instead of the system-provided libcxxrt (which I wrote, so can help debugging a bit better). --=20 You are receiving this mail because: You are the assignee for the bug.=
