Bug ID: 120172
Summary: Preprocessor error leads to cascading failures in
standard header instantiations
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mario.rodriguezb1 at um dot es
Target Milestone: ---
The compiler emits a massive cascade of errors and internal failures due to an
incomplete or malformed #include directive. A missing file name after #include
leads not only to a preprocessing error but triggers downstream parsing and
template instantiation errors in <chrono> and <ratio>, potentially due to
incomplete preprocessed input.
```
#include <cstddef>
#include <cwchar>
#include
<atomic>
#include <chrono>
#include <condition_variable>
#include <functional>
```
Compiler return code 143, after showing an unexpected behaviour, to quicly
reproduce:
