New issue 1578 by [email protected]: JSON.stringify sometimes segfaults
on ARM
http://code.google.com/p/v8/issues/detail?id=1578
I am trying to run Node.js on an at91SAM9g45 based embedded linux system.
I have been getting intermittent segfaults while testing. After much
digging it seems to happen mainly while stringifying larger objects (~25
KB), but I have seen it happen on smaller objects too. I have been using a
v8 dynamic library, and a very simple program that runs a script passed
through the command line to track this down. When I run a script that
stringifys a large object 100 times both node and my custom program
segfault about 20% of the time. For comparison I also use a modified
version of json2.js to stringify, runtime is much slower with this method,
but I have yet to see a segfault.
I have attached the source for my test program and the script I was using.
Here is what the output from the script looks like:
