Created attachment 173106 [details] gdb backtraces webkitgtk 1.8.3 works like a charm on OpenBSD, be it amd64/i386/powerpc/sparc64 (somewhat for the latter) and is being worked on for mips64el & hppa. 1.10.1 introduced an annoying regression : it works fine on ppc/sparc64(somewhat)/mips64el, but crashes right away on amd64 & i386 when starting GtkLauncher, be it with gtk2 or gtk3. We've suspected a JIT engine problem (since it seems to be the first difference between the working and broken archs), but the crashes happen too with a --disable-jit build. Atm it's a problem for us, because we cant update webkit in our ports tree and more and more things depend on the latest version. Attaching a bunch of gdb backtraces for all threads on an amd64 GtkLauncher, in case it rings a bell to anyone..
We no longer maintain this branch unfortunately. If you see the problem with a modern version, feel free to reopen.
