<pre>I am testing Clang Static Analyzer (CSA) on this code sample:
int main()
{
int* c = new int[10];
free(c);
int* d = new int;
free(d);
int* e = (int*)malloc(10);
delete e;
}
For testing I have built clang from trunk and run analysis as
'./scan-build -k --use-analyzer=clang ./clang++ main.cpp'. Then I get
only one report about first bug:
main.cpp:11:14: warning: Memory allocated by 'new[]' should be
deallocated by 'delete[]', not free()
free(c);
^~~~~~~
1 warning generated.
scan-build: 1 bug found.
No information about errors on the next lines. When I comment first two
lines with bug, CSA is able to find next bug and so on.</pre>
