Haakon - can you give us a bit more detail than this? When it happens, etc, would be useful.

[haakon]

The segfault happens because of xhr long polling requests used by for instance PubNub. If a network request is open when the simulator is reloaded, the simulator crashes.

Hope this helps

@Haakon

We have pushed a minor change to the way we cancel network requests and that should appear in daily builds, however the stack trace for the issue looks slightly different than yours. Could you provide additional detail on the actual request call you are making?

Regards,

Bryan

Hi,

unfortunately the new daily did not solve the issue. Here’s the xcode stack trace:

@atout, can you tell me more about your program?  Are you using the same networking API calls as the above post or are you just getting a SIGSEGV and not having any luck finding it?

SIGSEGV or Segment Violations happen when the program tries to access (and usually execute a block of code at) a memory location that your app doesn’t have access to.  This is typically due to a pointer to a function getting blown away and later a call back tries to access that function, but the address is no longer valid.

Typical situations where this happens is if you have an onComplete listener on a piece of audio and you’re using storyboard and you end up leaving the scene and that code’s not around for the audio to go to.  It could happen with timers or transitions, just about anything that has an onComplete and that module goes away.

@atout, can you tell me more about your program?  Are you using the same networking API calls as the above post or are you just getting a SIGSEGV and not having any luck finding it?

SIGSEGV or Segment Violations happen when the program tries to access (and usually execute a block of code at) a memory location that your app doesn’t have access to.  This is typically due to a pointer to a function getting blown away and later a call back tries to access that function, but the address is no longer valid.

Typical situations where this happens is if you have an onComplete listener on a piece of audio and you’re using storyboard and you end up leaving the scene and that code’s not around for the audio to go to.  It could happen with timers or transitions, just about anything that has an onComplete and that module goes away.
