FINAL RESULTS:

data/fcitx5-lua-5.0.0/src/file2cstring/file2cstring.cpp:25:5:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
    char buffer[1024];
data/fcitx5-lua-5.0.0/src/addonloader/luaaddonstate.cpp:384:16:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
    auto len = strlen(str);
data/fcitx5-lua-5.0.0/src/file2cstring/file2cstring.cpp:16:9:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
    if (strlen(argv[1]) == 0) {
data/fcitx5-lua-5.0.0/src/file2cstring/file2cstring.cpp:31:12:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
        in.read(buffer, sizeof(buffer));
