** [bugs:#1181] iem_tab crash at loading on 64bit linux**

**Status:** open

line 42 of `tab_sqrt.c` triggers a stack smashing on my Ubuntu 14.10 64bit system with pd 0.46-4.

line 42 is : 
`*(unsigned int *)(&f) = l;`

On my system : 
`printf("size of t_float : %d, long : %d, unsigned int: %d\n", sizeof(t_float), sizeof(long), sizeof(unsigned int));`

shows : 
`size of t_float : 4, long : 8, unsigned int: 4`

while on 32bit long is 4 byte wide.

and obviously, one can't cast a 8 byte wide variable into a 4 byte wide one without any care.
