Bug ID: 116424
Summary: ICE in cp_gimplify_expr, at cp/cp-gimplify.c:904
creating static object from other static objects
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dansimon09 at gmail dot com
Target Milestone: ---
I'm encountering an ICE with gcc-14.0.1 on ubuntu24.04 when compiling the
following code. I also see the error reproduced with gcc-trunk on compiler
explorer.
Code:
```c++
#include <ranges>
#include <CLI/CLI.hpp>
#include <fmt/format.h>
class EndsWithValidator: public CLI::CustomValidator {
public:
EndsWithValidator(std::string ext, bool case_sensitive = true)
noexcept(false) : CLI::CustomValidator() {
desc_function_ = [desc=fmt::format("Ends With {}", ext)](){ return
desc; };
name_ = fmt::format("String Ends With {} Validator", ext);
non_modifying_ = true;
if (case_sensitive) {
func_ = [ext=std::move(ext)](const std::string& string){
return string.ends_with(ext) ? std::string{} :
fmt::format(R"(String "{}" does not end with "{}")",
string, ext);
};
} else {
std::ranges::for_each(ext, [](auto& c){ c = std::tolower(c); });
func_ = [ext=std::move(ext)](std::string string){
std::ranges::for_each(string, [](auto& c){ c = std::tolower(c);
});
return string.ends_with(ext) ? std::string{} :
fmt::format(R"(String "{}" does not end with "{}" (case
insensitive))", string, ext);
};
}
}
};
static const CLI::CustomValidator ExtensionJSONGLTFValidator =
EndsWithValidator(".gltf", false);
static const CLI::CustomValidator ExtensionGLBValidator =
EndsWithValidator(".glb", false);
static const CLI::CustomValidator
ExtensionGLTFValidator(ExtensionJSONGLTFValidator | ExtensionGLBValidator);
```
Compiler output:
```
