Johan Tibell and I discovered what we're pretty sure is a bug in
the newArray# docs, in that it claims that it accepts a byte count,
not a word count. This appears to be falsified by GHC.Prim
as well as the actual implementation in C--:
unsafeArray b ies = unsafeArray' b (rangeSize b) ies
unsafeArray' (l,u) n@(I# n#) ies = runST (ST $ \s1# ->
case newArray# n# arrEleBottom s1# of
and
stg_newArrayzh
{
W_ words, n, init, arr, p, size;
/* Args: R1 = words, R2 = initialisation value */
Cheers,
