Merge pull request #2129 from felixhandte/fix-cctx-size-estimate 
Fix ZSTD_estimateCCtxSize() Under ASAN
 2020-05-11 16:36:46 -07:00
W. Felix Handte c6636afbbb Fix ZSTD_estimateCCtxSize() Under ASAN 
`ZSTD_estimateCCtxSize()` provides estimates for one-shot compression, which
is guaranteed not to buffer inputs or outputs. So it ignores the sizes of the
buffers, assuming they'll be zero. However, the actual workspace allocation
logic always allocates those buffers, and when running under ASAN, the
workspace surrounds every allocation with 256 bytes of redzone. So the 0-sized
buffers end up consuming 512 bytes of space, which is accounted for in the
actual allocation path through the use of `ZSTD_cwksp_alloc_size()` but isn't
in the estimation path, since it ignores the buffers entirely.

This commit fixes this.

programs/Makefile: make it actually work with clang
