mtxn at duck dot com <mtxn at duck dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #62160|0 |1 is obsolete| | --- Comment #3 from mtxn at duck dot com <mtxn at duck dot com> --- Created attachment 62172 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=62172&action=edit complete testcase of this bug. 'throw' is generating the previously mentioned error messages relating to 'typeinfo'. Virtual classes and methods must have a declaration and definition in the same compilation unit, otherwise the “vtable” symbols for them will not be generated. (sorry for 'soon™')
