Hi guys,
I found a bug in the latest version of header.cc in libcharls
In some cases Jpeg LS files could not be displayed. The "_rect" structure in JLSInputStream is not initialized.

 220 JLSInputStream::JLSInputStream(const BYTE* pdata, size_t cbyteLength) :
 221                 _pdata(pdata),
 222                 _cbyteOffset(0),
 223                 _cbyteLength(cbyteLength),
 224                 _bCompare(false),
 225                 _info(),
 226                 _rect()
 227 {
 228         ::memset(&_info, 0, sizeof(_info));
 229 }

 220 JLSInputStream::JLSInputStream(const BYTE* pdata, size_t cbyteLength) :
 221                 _pdata(pdata),
 222                 _cbyteOffset(0),
 223                 _cbyteLength(cbyteLength),
 224                 _bCompare(false),
 225                 _info(),
 226                 _rect()
 227 {
 228         ::memset(&_info, 0, sizeof(_info));
 229         ::memset(&_rect, 0, sizeof(_rect));        << missing
 230 }
