compile cppcheck with "-std=c++0x -O2", except for the file
"lib/symboldatabase.cpp" which additionally needs "-mllvm -enable-newgvn".
cppcheck will then crash when selfchecking
./cppcheck .
on the file cli/filelister.cpp with the configuration _WIN32
Internal error: cppcheck received signal SIGSEGV - SEGV_MAPERR (reading at
0x26f6000). Stackoverflow?
*** Error in `./cppcheck': malloc(): memory corruption (fast):
0x00000000025e03e0 ***
which does not happen if symboldatabase.cpp is compiled without newgvn.</pre>
