is it initialized

[Yakov Lerner]

Array md4_buf[] is used uninitialized in line 194 lib/genrand.c
for all I can see (function generate_random_buffer()) .

I can see possibility why this can be intentional () (... in order
to increase  entropy of the generated output ? ... but this still
looks weird .. no explanatory comment ... )

Is this indeed intentional ?

Thanks

.... snip ... md4_buf not mentioned here ...
