|

|
||||
(a) Check for malloc failures when getting memory for the ovector (POSIX) or
|
||||
the match data block (non-POSIX).
|
||||
|
||||
2. In the 32-bit library in non-UTF mode, an attempt to find a Unicode property
|
||||
for a character with a code point greater than 0x10ffff (the Unicode maximum)
|
||||
caused a crash.
