Bug ID: 80559
Summary: Segmentation fault on invalid initialiser list
template arguments
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: matt at godbolt dot org
Target Milestone: ---
Build: GCC v8.0.0 (built from source 20170428)
The following code:
----
#include <initializer_list>
template <typename T, std::size_t N>
struct Stack_t {};
template<typename T>
constexpr Stack_t(std::initializer_list<T> l) -> Stack_t<T, l.size()>;
----
Yields the following errors, and ends with mmap() failing to allocate memory:
<source>:7:69: error: template argument 2 is invalid
constexpr Stack_t(std::initializer_list<T> l) -> Stack_t<T, l.size()>;
^
<source>:7:69: error: template argument 2 is invalid
<source>:7:69: error: template argument 2 is invalid
<source>:7:69: error: template argument 2 is invalid
<source>:7:50: internal compiler error: Segmentation fault
constexpr Stack_t(std::initializer_list<T> l) -> Stack_t<T, l.size()>;
^~~~~~~
mmap: Cannot allocate memory
