[Bug c++/79582] New: Wrong mangled name for stdcall functions with templated arguments when referenced directly from vtbl.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79582 Bug ID: 79582 Summary: Wrong mangled name for stdcall functions with templated arguments when referenced directly from vtbl. Product: gcc Version: 6.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: jacek at codeweavers dot com Target Milestone: --- Created attachment 40764 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40764=edit test case It was originally reported in mingw-w64 build of Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=1336527 The attached test case shows the problem: $ i686-w64-mingw32-g++ -c test.i -o test.o $ i686-w64-mingw32-nm child.o |grep test_virtual U __ZN6Parent12test_virtualE16templated_structIiE@4 Note that stdcall suffix should be @8: the function has both implicit this pointer and templated struct of pointer size. I experimented with this a bit and it seems to be caused by a combination of stdcall and templated argument. The suffix is always @4 even if I add more simple arguments. The bug happens only if such function is needed by the vtbl itself. Other references to the function work as expected. I will also attach a test that shows the bug by failing to link: $ i686-w64-mingw32-g++ -c parent.cpp -o parent.o && i686-w64-mingw32-g++ -c child.cpp -o child.o && i686-w64-mingw32-g++ parent.o child.o -o test.exe child.o:child.cpp:(.rdata$_ZTV5Child[__ZTV5Child]+0xc): undefined reference to `Parent::test_virtual(templated_struct)@4' collect2: error: ld returned 1 exit status

[Bug c++/43093] [4.5 Regression] internal compiler error: Segmentation fault when compiling Firefox
--- Comment #2 from jacek at codeweavers dot com 2010-02-16 14:38 ---
Here is simplified test:
struct S {
int x;
S(const S s) {}
};
S __attribute__((__stdcall__)) getS();
void test()
{
S s = getS();
}
It seems like calling stdcall function that returns a struct (or class) with
copying constructor causes the problem.

--- Comment #12 from jacek at codeweavers dot com 2009-10-09 13:24 --- (In reply to comment #6) Not a regression any more. It is a regression now. It worked in 3.4 and doesn't work in 4.x. That's why I'm still using GCC 3.4.6. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=9381
