Description:
GCC seems to crash when writing this OpenMP clause within a lambda. Writing the loop outside the lambda is fine and defining the variable sum inside the lambda is also fine but this combination seems to crash GCC.

Code:
int main() {
double sum;
const auto task = [&] {
#pragma omp parallel for schedule(static) reduction(+: sum)
for(int i = 0; i < 1; ++i)
sum += 1;
};
task();
}

Compiled with:
g++ main.cpp -fopenmp

Output:
during RTL pass: expand
main.cpp: In lambda function:
main.cpp:4:17: internal compiler error: in make_decl_rtl, at varasm.c:1340
4 | #pragma omp parallel for schedule(static) reduction(+: sum)
