Assertion failed building parallel-hashmap

[monica__nicolo]

I can't manage to compile the header only parallel hashmap library with the latest icc (19) on Windows 10 

https://github.com/greg7mdp/parallel-hashmap

Just including the header ( <parallel_hashmap/phmap.h>), create a basic hashmap, and compiling with the suggested building options (c++ 11 support), and I get the following error:

#include <parallel_hashmap/phmap.h>
int main()
{
	phmap::flat_hash_map<unsigned int, unsigned int> sides_table;

}

assertion failed at: "shared/cfe/edgcpfe/lower_init.c", line 7013 

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\include\parallel_hashmap\phmap.h    1202    
 

With the visual studio compiler, it works fine. 

Thank you very much

What Visual Studio version are you using?

[POPOVITCH__STEVEN]

Using this: Intel® System Studio 2019 Update 3 Integration for Microsoft* Visual Studio* 2017, Version 19.0.6.15, 

This program crashes the compiler:

#include <parallel_hashmap/phmap.h>
int main()
{
    // Create an unordered_map of three strings (that map to strings)
    phmap::flat_hash_map<int, int> email;
    return 0;
}

However if you initialize the hash map it builds fine... Following program compiles:

#include <parallel_hashmap/phmap.h>
int main()
{
    // Create an unordered_map of three strings (that map to strings)
    phmap::flat_hash_map<int, int> email = { { 1, 1 } };
    return 0;
}

Intel® System Studio 2019 Update 3 Integration for Microsoft* Visual Studio* 2017, Version 19.0.6.15, 

Actually this simpler program crashes the compiler:

#include <parallel_hashmap/phmap.h>

struct Empty {};
 
int main()
{
    phmap::container_internal::CompressedTuple<Empty> x{{}};
    return 0;
}

I am the author of parallel_hashmap, so if  you can suggest a way to avoid this issue by changing the code I'll be happy to incorporate it.
