Thanks for having a look! So in the example from the issue, i.e.:
```c++
static inline int parse(int* i) {
return [&] -> int { return i[0]; }();
volatile bool b = false;
if (b) {
auto identifier = [&] -> int { return i[1]; }();
return identifier;
}
}
```
...the `ManglingContextDecl` of the second lambda is the `VarDecl` of the local
variable `identifier` (some debug output):
```txt
40 Var
VarDecl 0x56343b9495b8 <clang/test/Modules/pr178893.cppm:17:15, col:20> col:20
in mod hidden identifier 'auto'
```
I want it to be `DC` instead, which is the `DeclContext` containing the lambda:
```
35 CXXMethod
CXXMethodDecl 0x56343b922cb0 <clang/test/Modules/pr178893.cppm:10:7, col:37>
col:25 in mod hidden parse 'int (int *)' static inline
`-ParmVarDecl 0x56343b922b60 <col:31, col:36> col:36 in mod hidden used i 'int
*'
```
So this is the `DeclContext` of the `parse` function, which is also the
mangling context of the first lambda, IIUC. This is what you meant by the
parent DC, right?

I had a look in Compiler Explorer, and GCC generates code for both lambdas. But
I haven't looked at GCC's code.
