rcp nullptr assertion failure with global constants #2057
Description
Here's a simplified example:
#include <symengine/expression.h>
const auto a = ::SymEngine::Expression{1};
const auto b = -a;
const auto c = -a;
auto main() -> int
{}output:
SYMENGINE_ASSERT failed: external/symengine/symengine/symengine_rcp.h
function operator->(), line number 147 at
