WebPositive crashes on open with "invalid opcode exception"

[bradsco]

Opening WebPositive results in an error dialog. No main window is displayed.

IIRC HaikuWebKit requires SSE2 which Pentium III doesn't have.

Duplicate of #10304.

There was a regression in the latest release but it will be fixed again in the next one (already done in webkit sources).

"... it will be fixed again in the next one" 27.04.2018 - issue is actual for now.

[pulkomandy]

Yes, still didn't make a WebKit release since then.

[R0bur]

I think that WebKit will not patch this issue. They are right: P-III is deprecated CPU. Maybe there is an ability to modify WebPositive to disable multimedia features when running on the old hardware?

See here this was discussed at length on the mailing list already. ​https://www.freelists.org/post/haiku-development/Fwd-webkitdev-Proposal-Not-supporting-x86-wo-SSE2,8

It is unlikely that webkit will have SSE patched out, most likely is that Netsurf will be bundled for older machines instead of Webpositive it is also a rather nice browser with a native interface though not as featureful as Webpositive.

[pulkomandy]

It's not just about multimedia features. WebKit needs SSE support also for the javascript code they generate, and I'm not going to spend much effort avoiding that.

Replying to pulkomandy, cb88: Thank you for the clarification of the issue.
