Hi,

as title says, if I compress a allocated (zeroed) buffer of (0x800000 + 1) bytes, the result of BrotliCompressBuffer can not be decompressed using BrotliDecompressBuffer.
As there are no error-codes or messages, I dont know what the problem is.

testing under OS X 10.10.5

thank you

ok, now I see that only BrotliDecompressedSize does not work. Compressing itself works fine if I manually set the size.
