Subject: Iceweasel Random Crash While Running _javascript_




We are using Iceweasel on an arm target running Squeeze, and we are running into an issue with Iceweasel.  Our target device is being used as an UI which is displaying _javascript_ hosted by another device.  We are seeing Iceweasel crash by a mix of segmentation faults and illegal instructions after running for an apparently random length of time (few minutes to hours).  We have multiple _javascript_ stack dumps that show the same _javascript_ function being executed when we crash, although the crash is happening on different lines of code each time.  This _javascript_ function is being executed frequently (every couple of seconds).  We also have strace logs and gdb backtraces that show Iceweasel is generating machine code for the _javascript_ and the crash appears to be in the same memory block that the _javascript_ code is being executed from. 


Do you know someone who might be willing to help us determine the root cause of why Iceweasel is crashing?
