*p_1(D) = _Literal (int[]) {};
}
Build with gcc -fgimple, and stack trace:

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.
Reproduced up to 10.3 with assertion (the oldest version on gcc.godbolt), and I
assume there are more affected compiler versions.
