<pre>
If a instance of the `msg` struct does not exist in the `msg` module, the `send` module causes clang to segfault with little information given.
However, if a `void a() { msg a; }` or simply `msg a;` occurs at the end of the `msg` module, everything compiles and works. The example below is very fragile and also depends on `std::equal_to<string_type>` to produce the error. I was unable to find a root cause for this since the backtrace was not very useful.
FILE **msg.cc** (compiles)
[generated preprocessed source](https://github.com/llvm/llvm-project/files/9164587/msg-00472d.cpp.txt)
[generated run script](https://github.com/llvm/llvm-project/files/9164590/msg-00472d.sh.txt)
```c++
module;
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/containers/string.hpp>
#include <boost/interprocess/allocators/allocator.hpp>
#include <boost/unordered_map.hpp>
export module msg;
namespace ipc = boost::interprocess;
export struct msg {
using manager = ipc::managed_shared_memory::segment_manager;
using string_type = ipc::basic_string<char, std::char_traits<char>, ipc::allocator<char, manager>>;
boost::unordered_map<int, int, boost::hash<int>, std::equal_to<string_type>> envadds;
};
```
FILE **send.cc** (clang segmentation fault)
[-E preprocessed_source](https://github.com/llvm/llvm-project/files/9164475/preprocessed_send.txt) (-gen-reproducer does not work)
```c++
module;
#include <boost/interprocess/containers/string.hpp>
#include <boost/unordered_map.hpp>
export module send;
import msg;
void a() { msg a; }
```
**if msg.cc is changed to this, send.cc compiles fine!**
```c++
module;
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/containers/string.hpp>
#include <boost/interprocess/allocators/allocator.hpp>
#include <boost/unordered_map.hpp>
export module msg;
namespace ipc = boost::interprocess;
export struct msg {
using manager = ipc::managed_shared_memory::segment_manager;
using string_type = ipc::basic_string<char, std::char_traits<char>, ipc::allocator<char, manager>>;
boost::unordered_map<int, int, boost::hash<int>, std::equal_to<string_type>> envadds;
};
void a() { msg a; }
```
**otherwise:**
```
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
