Bug ID: 109823
Summary: Internal segmentation fault for trailing return with
doubly expanded variadic pack
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rafel.perello at upc dot edu
Target Milestone: ---
Created attachment 55062
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55062&action=edit
Code
The following code makes the compiler crash if the trailing return with
decltype is added. If the lambda is defined without trailing return, the
program works as expected.

Reduced testcase:
int f(int){return 0;}
int main()
{
auto tensor_product = [](const auto &...arguments)
{
return [&](auto &&... inputs) -> decltype((... * arguments(inputs)))
{
return 0;
};
};
tensor_product(f)(1);
}

The testcase from comment #1 started ICEing with commit dc58fa9f3142097b (Jason
Merrill: PR c++/84036 - ICE with variadic capture).
