Bug ID: 48128
Summary: clang++ fails create local function inside local
structure in template function
Product: clang
Version: 11.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++2a
Assignee: unassignedclangbugs at nondot.org
Reporter: erstrauss at gmail.com
CC: blitzrakete at gmail.com, erik.pilkington at gmail.com,

The the program below creates a local function inside a Local structure, and
adds the
local function address into the .init_array section in order to call that local
function at process start.
The localFunc template function is using a source_location const static
variable as template parameter.
See below output of the running program when the template instantiation is only
requested from inside simple function.
The clang++ crash happens when this template is called from within a template.
----------------
$ cat init_array3.cpp
#include <experimental/source_location>
#include <iostream>
using namespace std::experimental;
template<const source_location& X>
void localFunc(const char* name)
{
static int count{0};
volatile ::std::ios_base::Init dummy{};
std::cout << "post-main X: " << name << " " << X.file_name() << " " <<
X.line()
<< " &zount: " << (void*)&count << " count: " << (++count) << " "
<< __PRETTY_FUNCTION__ << std::endl;
struct Local
{
static void init()
{
volatile ::std::ios_base::Init dummy{};
std::cout << "pre-main init from localFunc: " << X.file_name() << "
"
<< X.line() << " &count: " << (void*)&count
<< " count: " << (++count) << " " << __PRETTY_FUNCTION__
<< std::endl;
}
};
static void* volatile initp
__attribute__((__used__, section(".init_array"))){(void*)&Local::init};
}
#define LOCAL_FUNC(NAME) \
do \
{ \
constexpr static auto s = source_location::current(); \
localFunc<s>((const char*)&(NAME)[0]); \
} while (0)
void okFunc() { LOCAL_FUNC("X1"); }
template<typename T>
void funcA(T)
{
LOCAL_FUNC("XT2");
}
int main()
{
std::cout << "main() started" << std::endl;
okFunc();
funcA<int>(1); //**** the template creates local function for the template
instantiation.
return 0;
}
----------------
if the //**** line is commented out, the compiled program works and output the
following:
----------------
$ ./init_array3
pre-main init from localFunc: init_array3.cpp 38 &count: 0x404198 count: 1
static void localFunc(const char *)::Local::init()
main() started
post-main X: X1 init_array3.cpp 38 &zount: 0x404198 count: 2 void
localFunc(const char *) [X = s]
----------------
