# Line 2  ChangeLog for PCRE Line 2  ChangeLog for PCRE
2  ------------------  ------------------
3    
4    
5    Version 1.07 16-Feb-98
6    ----------------------
7    
8    1. A pattern such as /((a)*)*/ was not being diagnosed as in error (unlimited
9    repeat of a potentially empty string).
10    
11    
12    Version 1.06 23-Jan-98
13    ----------------------
14    
15    1. Added Markus Oberhumer's little patches for C++.
16    
17    2. Literal strings longer than 255 characters were broken.
18    
19    
20    Version 1.05 23-Dec-97
21    ----------------------
22    
23    1. Negated character classes containing more than one character were failing if
24    PCRE_CASELESS was set at run time.
25    
26    
27    Version 1.04 19-Dec-97
28    ----------------------
29    
30    1. Corrected the man page, where some "const" qualifiers had been omitted.
31    
32    2. Made debugging output print "{0,xxx}" instead of just "{,xxx}" to agree with
33    input syntax.
34    
35    3. Fixed memory leak which occurred when a regex with back references was
36    matched with an offsets vector that wasn't big enough. The temporary memory
37    that is used in this case wasn't being freed if the match failed.
38    
39    4. Tidied pcretest to ensure it frees memory that it gets.
40    
41    5. Temporary memory was being obtained in the case where the passed offsets
42    vector was exactly big enough.
43    
44    6. Corrected definition of offsetof() from change 5 below.
45    
46    7. I had screwed up change 6 below and broken the rules for the use of
47    setjmp(). Now fixed.
