Summary: [4.7 regression] g++.dg/torture/pr41257-2.C FAILs to
link on Tru64 UNIX
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: link-failure
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
Host: alpha-dec-osf5.1b
Target: alpha-dec-osf5.1b
Build: alpha-dec-osf5.1b
Between 20110502 and 20110518, g++.dg/torture/pr41257-2.C started to FAIL
on Tru64 UNIX:
A::~A()
typeinfo for A
collect2: error: ld returned 1 exit status
which is a link error (undefined symbols). This is a regression from the 4.6
branch. While the input file is identical, the generated code is far longer on
mainline, and contains a call to an undefined function _ZN1AD2Ev (A::~A()).
This may be related to the fact that Tru64 UNIX doesn't support weak
definitions,
but the code is plain wrong.
I'm attaching assembler output from 4.6 and 4.7.
