The test g++.dg/abi/vtt1.C is failing with "-funit-at-a-time" (or optimization "-O" or higher since this enables "-funit-at-a-time" by default).
GCC 4.x.y doesn't seem to be affected. Since this behaviour can be triggered with just "-O2" I rate this as a regression (although "-funit-at-a-time" was introduced in 3.4.0). Gaby, do you think that this is a showstopper for 3.4.5 or not? -- Summary: [3.4 Regression] g++.dg/abi/vtt1.C failure with "-funit- at-a-time" Product: gcc Version: 3.4.5 Status: UNCONFIRMED Keywords: ABI Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: reichelt at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25163
