Bug ID: 38963
Summary: Warn when dereferencing pointer immediatelly after
allocation using malloc
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: david.bolvan...@gmail.com
CC: llvm-bugs@lists.llvm.org
void x(void) {
int *p = (int *)malloc(sizeof(int));
if (*p)
abort();
}
LLVM seems to optimize it to just abort() - that's fine.
But we should warn under -Wuninitialized. Currently, there is no warning when
compiling with -Wall.
+ realloc? aligned_alloc?
