Details

When opening a .rock file with text_editor in Rockbox Vesion 3.3 on a Sansa e200 series the player crashes. After scrolling to a certain point (you might have to scroll to the end and back up again), the player crashes (you have to hold power for 30 seconds to turn it on) and displays "Divide by zero at 00063A2C (0)". The same code appears every time.
This task depends upon

Can you upload the text file? I tried a really long file and it didn't happen.

Shouldn't he start with testing on a current build? 3.3 is rather out of date.

Happens on my Current Build e200 too. When I open a long, complex file (a .rock file for example).

small text file also can cause the "Divide by zero" :)

I was exploriing this bug more, and I discoverd that if you opan an extremely large (I'm assuming) file such as chip8.rock the player never opens the file. Instead it will immediately crash and display the same divide by zero message.

I also tried lots of files, big, small, empty ones. I also tried your (teru) file but it didn't crash. Does this bug still exists ? Can you provide more explain files ?
