Hi. Looks you hit stack overflow. In that case, please use ulimit and set
smaller stack, that will simplify the reduction. You have to properly write
creduce script that will catch the ICE:
https://gcc.gnu.org/wiki/A_guide_to_testcase_reduction

And please use -fmax-errors=1 which will guarantee that reduced test-case will
be a valid code.

Please either download debug symbols for GCC package. Or build your own from
source: https://gcc.gnu.org/install/configure.html

Feel free to ask for questions..
