How do I decipher FireFox crash report

Get help using Construct 2

Post » Sun Mar 06, 2016 1:56 pm

While testing my current project I encounter this crash after about 10 mins of run time, fps drops significantly, Object count remains less than 200 and cpu usage hasn't been a good gauge, last time I observed the crash, debugger said cpu usage was around 30%, but normally while the games running it says around 70-80%. My assumption is that it's something a memory leak or bad code somewhere but I don't know how to decipher the crash report and thus where to start looking. Is there anyway to tell why/where the memory is being eaten?

Maybe someone can tell me how to view function logs?

I see from the shift + cntrl + k console log something like
saved state to indexedb adding up storage space, any idea what causes it?
update - I'm retarded and left an old piece of code to save the game state with no conditions, so it just constiniously saved

Now I'm seeing [Construct 2] Function object: used 'Param' expression when not in a function call I wonder if it's normal function logging or an error involving one


Crash report below

It's obviously a memory related crash but debugger isn't giving me any clues as to why, it's not too many instances

Hi,

Im not quite sure, but you may got a variable/integer that goes crazy:

IPCFatalErrorMsg: Error deserializing 'length' (uint32_t) of 'IndexUpdateInfo[]'


If my suspiction is right, check all variables and calculations you got in your project (maybe a function which calls itself messes them up), this might help you out: https://msdn.microsoft.com/en-us/library/5kzh1b5w.aspx & https://msdn.microsoft.com/en-us/library/x0sksh43.aspx - but how I said, Im not 100% sure about that ;-)
