Issue ID: 24298
Summary: cpp_delete should check for null
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: normal
Priority: P1
Component: druntime
Assignee: [email protected]
Reporter: [email protected]
Function core.stdcpp.new_.cpp_delete is the equivalent of the delete operator
in C++, which can be called with a null pointer and ignores it. Calling
cpp_delete with a null pointer can currently result in a crash, which makes
porting of C++ code to D harder.

{
import core.stdcpp.new_: cpp_new, cpp_delete;
extern(C++) static struct S
{
__gshared int numDeleted;
__gshared int lastDeleted;
int i;
~this()
{
lastDeleted = i;
numDeleted++;
}
}
S *s = cpp_new!S(12345);
cpp_delete(s);
assert(S.numDeleted == 1);
assert(S.lastDeleted == 12345);
s = null;
cpp_delete(s);
assert(S.numDeleted == 1);
assert(S.lastDeleted == 12345);
}
