I was playing around with Safari the other day and noticed that it crashes solid if you convince it to visit:
Typing it into the address bar is sufficient for testing and crashes the browser completely. I loaded up Safari in gdb to see where it crashes and got the following result:
> Program received signal EXC_BAD_ACCESS, Could not access memory. > Reason: KERN_INVALID_ADDRESS at address: 0x076fffff > [Switching to process 266 thread 0x6403] > 0xffff8ce4 in ___memcpy ()
The fact that random data from the Internet is causing problems with memcpy worries me. I haven't figured out how to change the arguments to memcpy, but it seems possible. Hopefully someone that knows more about debugging threaded Objective-C programs running on PPC can look into it. I'm more of a simple x86/C person myself :)
Just for reference, it seems that Safari needs a very specific set of inputs to actually crash:
data://<h>/ doesn't crash but data://<h>/< does
(also data://<crash>test</crash> doesn't crash... the h in <h1> seems important somehow).
