The mprotect error is already tracked in #16898.

Do you reproduce the stack trace that you have attached to this ticket, that is different?

In general, please do not put multiple different problems in the same ticket. It makes it impossible to track what is fixed and what isn't.

Ref: https://dev.haiku-os.org/ticket/16649

Ok. YOu can close this ticket. I'll just retest when MMAP implementation is fixed.

Updated for hrev55399 x86_64:

  1. ​​https://github.com/ - no issues (changed)
  2. ​​https://github.com/haiku - no issues
  3. ​​https://disneyworld.disney.go.com/ - Web+ will exit program during loading page (no crashes to Debugger) or halt operation (i.e. can't transition to another web page). If I use libroot_debug, Web+ will just halt on web page without program exit. (changed)

This issue is unrelated to mmap, it was in relation to mprotect. fix is tracked in #16898.

Can you reproduce the other trace you have in this ticket with specific steps?

comment:7 by cocobean, 3 years ago

mprotect is the baseline for mmap functionality.

Ok. I just rebooted the machine. Did this: 

strace WebPositive https://disneyworld.disney.go.com/

This worked. The page video animation works like Otter Browser MSE. No crashes.

I then retried after another reboot. 

WebPositive https://disneyworld.disney.go.com/

The main crash issue is resolved now. But Web+ now seems to lose the top video animation. That is another bug report.

Thanks! Ticket resolved!

The fix for mprotect is not merged yet... so i really don't see how it could have been resolved, unless you were talking about the unrelated issue to netservices.
Anyhow, since you can't reproduce this anymore I'll close the ticket
