jaja stits on the stack, not the heap.  

You need to increase the size of your stack space with teh 'ulimit'
command.   It's also possible that the sysadmin set a hard limit 
at 8meg or 24 meg. in which case you need the sysadmins help to raise
it.

You can try using malloc to put it on the heap or try 
'static float jaja[10000]' to put it in the bss.
