Describe the bug

I build the library v1.5.4 with CMake on ubuntu 20.04, but failed to run, and noticed some weired behaviors.

Debug build

The compress call will crash, log is here:

/home/king1234/workspace/reqable/reqable-compress/third_party/zstd/lib/compress/zstd_compress.c:5802: ZSTD_createCStream 
/home/king1234/workspace/reqable/reqable-compress/third_party/zstd/lib/compress/zstd_compress.c:5952: ZSTD_initCStream 
reqable: /home/king1234/workspace/reqable/reqable-compress/third_party/zstd/lib/compress/zstd_compress.c:5966: ZSTD_nextInputSizeHint: Assertion `cctx->appliedParams.inBufferMode == ZSTD_bm_buffered' failed.

Release build

The compress call seems to be ok now.

/home/king1234/workspace/reqable/reqable-compress/third_party/zstd/lib/compress/zstd_compress.c:5802: ZSTD_createCStream 
/home/king1234/workspace/reqable/reqable-compress/third_party/zstd/lib/compress/zstd_compress.c:5952: ZSTD_initCStream 
/home/king1234/workspace/reqable/reqable-compress/third_party/zstd/lib/compress/zstd_compress.c:6977: ZSTD_endStream : remaining to flush : 0

But the decompress might be crash:

/home/king1234/workspace/reqable/reqable-compress/third_party/zstd/lib/decompress/zstd_decompress.c:1672: ZSTD_createDStream 
/home/king1234/workspace/reqable/reqable-compress/third_party/zstd/lib/decompress/zstd_decompress.c:1750: ZSTD_initDStream

Sometime throws an error:

I have set DEBUGLEVEL from 0 to 10, and only got those logs, I checked the source code and found this to be very unusual, but I couldn't explain it. I also tried clang compiler, and -O0 flags, but got the same results.

On other platforms, like Android, Windows and Mac, I can confirm that the library works well. For the same input, the logs on Mac:

I build the library v1.5.4 with CMake on ubuntu 20.04

Why v1.5.4 ?
Current release is v1.5.7.

@Cyan4973 I tried, v1.5.7 has the same issue.

@MegatronKing These issues are unexpected.

  1. Do you have local modifications to the library? If you delete the zstd directory and re-download from v1.5.7 does it still occur?
  2. Are other libraries having similar unexplained issues on that system?
