Re^3: perlembed segmentation fault by 4Xsake (Initiate) on Jul 25, 2012 at 11:03 UTC
I wish I knew how to be clear why the fault occured: The problem seems to occur in libperl.a and I stronlgly suspect it's when it calls perl_alloc(). I'll initially rule out memory leaks since my test app currently does nothing other than instantiate and invoke perl. Insufficient memory strikes a chord. I currently have a 2GB micro SD card which was initially pretty empty when I successfully ran my app. Since then I installed loads of things and almost filled the SD card (I have about 200MB left), so I certainly have much less disk space now than I had before. My confusion is this: I am low on disk space, not ram. As far as I know perl_alloc() requires ram and not SD card space so I can't see how low SD card space would cause a problem. I ran 'top' to see if any other processes were hogging ram but almost all of the ram seems to be available. I do think you're onto something here with the hole "freeing up space" but I don't understand why. Besides, 200MB is still a lot of disk space for one app. I can't delete much on the SD card, plus I'm afraid of deleting the wrong thing. As a stab in the dark, I'll go get a 16GB card from the supermarket and try again. Is this what you had in mind or did you mean freeing up memory some other way?	[reply]
