After upgrading from webkit-gtk-2.18.6 to webkit-gtk-2.20.3 creating reports in GnuCash fails (it uses webkit-gtk for rendering) and this error is printed to the terminal: FATAL: Primitive gigacage disabled, but we don't want that in this process I managed to trace this to having ulimit -v 9500000 set. With ulimit -v unlimited all works as expected. I think this is related to bug 183329 -- that's the one that gave me the clue that the problem was connected to the virtual memory limit. (I have vm.overcommit_memory = 0 if that makes any difference) At least I think the error message should be nicer even if it's "supposed to" fail. Running Gentoo Linux on x86. Kind regards, Anton
