When I open the settings, and do "enable jit compiler" then it takes 5 
seconds and gives me out of mem.

I did not see memory consumption raise during the 5 secs. So it likely 
was one sudden big alloc attempt.

After that compilation would not work : error empty string / file not 
found tmp/main

reloading the page and it works again, until I do enable jit again
