PKEuS 44a19b527e Use ValueFlow and SymbolDatabase to detect buffer overflows with new and malloc, improving support for enums (#7576) 2016-07-08 20:53:08 +02:00
PKEuS 644a216394 Fixed two false positives related to char arrays initialized by a literal:
- Run check for writing to string literals on non-simplified token list (#7283)
- Run buffer overrun checking for string literals on non-simplified token list (https://sourceforge.net/p/cppcheck/discussion/general/thread/2c33dfc5/)

PKEuS 8c0eab3eb3 Optimization: Improved performance of CheckBufferOverrun::checkScope() when dealing with a large number of arrays (#5975)
