https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253840 --- Comment #21 from Dimitry Andric <dim@FreeBSD.org> --- I've looked at the layout of struct _Unwind_Exception, which is declared in libcxxrt's unwind.h, and did some checks on the field offsets: ---------------------------------------------------------------------- amd64, before libcxxrt changes: offsetof(_Unwind_Exception, exception_class) =3D 0 offsetof(_Unwind_Exception, exception_cleanup) =3D 8 offsetof(_Unwind_Exception, private_1) =3D 16 offsetof(_Unwind_Exception, private_2) =3D 24 sizeof(_Unwind_Exception) =3D 32 amd64, after libcxxrt changes: offsetof(_Unwind_Exception, exception_class) =3D 0 offsetof(_Unwind_Exception, exception_cleanup) =3D 8 offsetof(_Unwind_Exception, private_1) =3D 16 offsetof(_Unwind_Exception, private_2) =3D 24 sizeof(_Unwind_Exception) =3D 32 i386, before libcxxrt changes: offsetof(_Unwind_Exception, exception_class) =3D 0 offsetof(_Unwind_Exception, exception_cleanup) =3D 8 offsetof(_Unwind_Exception, private_1) =3D 12 offsetof(_Unwind_Exception, private_2) =3D 16 sizeof(_Unwind_Exception) =3D 20 i386, after libcxxrt changes: offsetof(_Unwind_Exception, exception_class) =3D 0 offsetof(_Unwind_Exception, exception_cleanup) =3D 8 offsetof(_Unwind_Exception, private_1) =3D 12 offsetof(_Unwind_Exception, private_2) =3D 16 offsetof(_Unwind_Exception, reserved) =3D 20 sizeof(_Unwind_Exception) =3D 32 ---------------------------------------------------------------------- So in short, only on i386 has the struct become bigger, but this shouldn't influence any callers. (At least, if they aren't crazy enough to attempt to allocate and fill these by themselves... But libreoffice might be crazy eno= ugh) --=20 You are receiving this mail because: You are the assignee for the bug.=
