Bug ID: 39134
Summary: CSA doesn't show all bugs in function
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Static Analyzer
Assignee: dcough...@apple.com
Reporter: zamazan...@tut.by
CC: llvm-bugs@lists.llvm.org
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.
