APAR status
Closed as program error.
Error description
The compiler creates temporaries for various intermediate calcualtions. During the deletion of one such temporary, the delete of a constructor is failing to occur; resulting in a memory leak in the compiled application. =====Test case: #include <cassert> int ctor = 0; struct container{ container(){ ctor++; } container(const container& con){ ctor++; } ~container(){ ctor--; } int at(int a) { return 1; } }; container convertString( wchar_t *string ) { container result; return result; } void test() { int a = container(convertString( (wchar_t*)(L"<0x") )).at(1); } int main(void) { test(); assert(ctor==0); return 0; }
Local fix
