	* If the compiled file contents are the same as in already existing
	  file (left from previous compilation), the old file is retained.

	* [NEW PLATFORM] Compiled and tested on Linux @ alpha64 (LP64).
	  Some code needed to be fixed regarding int-long conversions
	  (mostly inside the test suite), and floating point handling
	  code needed to be restructured to handle signalling NAN and
	  other floating point exceptions quietly. Smooth transition!

	  optionals-laden indefinite length structure. The code was previously
	  refusing to parse such structures.
222
	* Fixed explicitly tagged ANY type encoding and decoding
223
	  (Severity: medium; Security impact: low).
224

	  When encoding data for certain ASN.1 specifications containing
	  explicit tags, the tag is always written incorrectly due to
	  incorrect memory reference. The encoding will almost always produce
	  unparseable data and might well reference unmapped region so program
	  would produce segmentation violation. Fortunately, memory is
	  read, not written, so remote exploits cannot execute arbitrary
	  code and triggering unmapped memory reference is highly unlikely
	  even it attacker knows the code (basically, the compiler should place
	  asn1_DEF_... right before the end of the mapped memory region, which
	  is extremely rare).

=== Bug importance disclosure terms ===

SEVERITY.
    This term applies to the frequence the particular construct is used
    in the real world. The higher the frequency, the more chances of triggering
    this bug.
	low:	The ASN.1 specifications which could trigger
		this kind of bug are not widespread.
	medium:	The particular ASN.1 construct is used quite often,
		so the chance of triggering an error is considerable.
	high:	This fix is considered urgent, or the particular ASN.1
		construct triggering this bug is in wide use.

SECURITY IMPACT.
    This term applies to the amount of potential damage a bug exploitation
    could cause.

	low:	The local exploitation is unlikely; the remote exploitation
		is impossible.
	medium:	The remote exploitation is possible when a particular ASN.1
		construct is being used. If possible, only hard failure, spin
		or memory leak are the possible outcome: no shellcode
		injection could possibly be carried by the attack.
	high:	The remote shellcode injection is possible, or the bug is
		otherwise remotely exploitable for most specifications.
