--- Comment #2 from Julien Nabet <[email protected]> ---
Caolán/Eike: I took a look at the BT included here and found toolkit, vcl and
sc parts.
3 libtllo.dylib Fraction::Fraction(Fraction const&)
./tools/source/generic/fract.cxx:60^M
4 libtllo.dylib Fraction::Fraction(Fraction const&)
./tools/source/generic/fract.cxx:61^M
5 libtllo.dylib Fraction::operator=(Fraction const&)
./tools/source/generic/fract.cxx:296^M
6 libvcllo.dylib MapMode::SetScaleY(Fraction const&)
./vcl/source/gdi/mapmod.cxx:127^M
7 libsclo.dylib ScGridWindow::GetDrawMapMode(bool)
./sc/source/ui/view/gridwin3.cxx:268^M
8 libsclo.dylib ScTabView::MakeDrawView(TriState)
./sc/source/ui/view/tabview5.cxx:244^M
After adding some debug logs, I compared the number of calls of Fraction ctr
and dtr and indeed, there's less call to dtr.
I tried to find why and noticed o3tl::cow_wrapper< ImplMapMode > ImplType at
frame 6
If there were just a dozen of them, I would take a bt of each to compare but
there are thousands of calls. I also tried to distinguished the 5 ctrs, hoping
to find a specific one called n times ("n" would have been the investigated
diff)
Any thoughts to keep on here?
Besides, frame 8 corresponds to:
244 pGridWin[i]->SetMapMode(pGridWin[i]->GetDrawMapMode());
and searching in SetMapMode, thought this patch for review
https://gerrit.libreoffice.org/#/c/42306/ may also be useful even if not for
the Fraction part indeed.
