Bug ID: 19629
Summary: failing to substitute into lambda-expression in
initializer of a variable template
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++1y
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
This code:
template<typename T> int var = [] {
struct S { int f() { return T(); } };
return S().f();
} ();
int k = var<int>;
crashes in IR gen, because we reused the LambdaExpr from the template
definition in the initializer of the template specialization.
Not clear whether we're not transforming it at all, or whether TreeTransform
somehow believes it can reuse the LambdaExpr.
