SECURITY fix: Prevent CRAM byte_array decoder from overflowing its output buffer. This could be triggered by certain malformed CRAM inputs. (PR #1934)
Two fixes for crashes reported when trying to save data with very long alignment records with sequence '*' as CRAM 3.1:
The htscodecs submodule is updated to v1.6.4. This includes a fix to the rANS encoder to prevent it from failing on these inputs. (PR #1935. Reported by Martin Pollard)
Improved error handling in cram_compress_block2(). If the previously-chosen CRAM compression method starts to fail, it will now try other methods instead of giving up immediately. (PR #1931. Reported by Martin Pollard)
Fix warnings due to the wrong datatype being passed to curl_easy_setopt() (PR #1925. Thanks to John Marshall)
Prevent instances of memcpy(out, NULL, 0), which is strictly undefined behaviour. (PR #1930. Thanks to Ben Lawrence).
Fixed compilation against older glibc / macOS SDKs that incorrectly suppressed some symbols if _XOPEN_SOURCE was defined. (PR #1928. Reported by John Marshall)
Fixed ref-cache configure check for libcurl, so that if libcurl is not available, or turned off by ./configure --disable-libcurl, the ref-cache build will be automatically disabled as well. (PR #1929, fixes #1926. Reported by biounix)
