Describe the bug

while trying to build with
forge build --dynamic-test-linking

Error (9097): Identifier already declared.
  --> contracts/.../MyContract.sol:62:5:
   |
62 |     struct ConstructorArgs {
   |     ^ (Relevant source part starts here and spans across multiple lines).
Note: The previous declaration is here:
 --> foundry-pp/DeployHelper231.sol:7:5:
  |
7 |     struct ConstructorArgs {
  |     ^ (Relevant source part starts here and spans across multiple lines).

• forge clean doesn't fix.
• It builds fine without this new flag
• forge build --dynamic-test-linking --skip test worked - so could be related

Unfortunately this was in a large private repo and I couldn't repro with a smaller example

@grandizzy not sure if there's some other log data I can gather which could help

@frontier159 thank you, yeah, looks like an edge case, can you scan your code base and see if you have any struct named ConstructorArgs declared? Thanks!
