UnlessUnless you are very sure of the rules about what combinations of leading underscore are reserved for the implementation I would suggest that you do not use underscore (_
) as a prefix. Please see this excellent answer for what identifiers are reserved.

I read the above as: i = a * 10 + m
. Lets call the lowest address that the system can assign to user heap or stack for a_min
, conversely call the largest address a_max
. The same goes for m
with m_min
and m_max
. The only way the above expression can be safe is if a_min*10 > mm_max
and a_min*10 > a_max
. I fired up my debugger and grabed the first heap pointer I could find: a_min <= {a=0x5a08c00} <= a_max
and the first instruction pointer {m=0x141533749} <= m_max
.
Note that a*10 = 0x38457800 < 0x141533749m=0x141533749 --> a_min*10 <!> mm_max
which means that you have collisions in your identity function. This is asking for trouble...
