--- Comment #4 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
I've submitted https://gcc.gnu.org/pipermail/gcc-patches/2025-April/681520.html
for the 15 regression with assembling OpenMP with modules.
When I try to build p1.cpp I get the following checking-only assertion:
p1.cpp:1:8: internal compiler error: in decl_node, at cp/module.cc:8994
1 | export module p1;

Please submit a full bug report, with preprocessed source (by using
-freport-bug).
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
The assertion is thrown when streaming the generated function "omp declare
reduction Op" because this is a DECL_LOCAL_DECL_P function but isn't on the
BLOCK of sum, so we didn't stream it by value when we were supposed to.
Building with this checking assertion disabled I get the error described in #c0
(which makes sense because we failed to properly stream the definition of this
function), so confirmed.
