crash file
$ clang-tidy-10 crash.c --
produces a segmentation fault
I have tried 7, 8 and 10 with the same results.
Please see attached, and here is the minimal code:
#include <stdio.h>
void __attribute((ownership_returns(my_malloc))) *malloc(size_t amt);
void __attribute((ownership_takes(malloc, 1))) free(void *ptr);
void __attribute((ownership_returns(my_malloc))) *my_malloc(size_t amt);
void test1() {
int *p = my_malloc(12);
free(p);
}
int main() {
return 0;
}
If I comment out the following line the segmentation fault goes away:
void __attribute((ownership_takes(malloc, 1))) free(void *ptr);</pre>
