Hi,
As reported here:
https://bugs.gentoo.org/show_bug.cgi?id=627814

Taking kmymoney git sources and building it using:
$ gcc -v
Using built-in specs.

Thread model: posix
gcc version 5.4.0 (Gentoo 5.4.0-r3 p1.3, pie-0.6.5)
Triggers a segmentation fault shown in the attachment. The code in question
seems to be:
auto removeCellFromRow = [=](auto &&self, QStandardItem *item) -> bool {
for(auto j = 0; j < item->rowCount(); ++j) {
auto childItem = item->child(j);
if (childItem->hasChildren())
self(self, childItem);
childItem->removeColumn(ixCol);
}
return true;
};
And Gentoo community reports gcc 6.4 builds it, and KDE community says clang is
able too. My wonder is, if this is a bug or a feature not yet implemented in
the version. If it's the previous, it would be awesome to get the fix
backported, otherwise, please let me know to consider to jump to the new
version.
Thanks!
José
