Crash when evaluating Stockfish NNUE

[Stefan-Mada]

This is using the splicer build.
I tried running supervec on the .ll file generated from the evaluate_nnue function in Stockfish, but supervec crashes.

In order to isolate the bug, I ran creduce on the src/nnue/evaluate_nnue.cpp file after I prepocessed it. From the src directory of Stockfish, I ran the following command:
clang++ -Wall -Wcast-qual -fno-exceptions -std=c++17 -pedantic -Wextra -Wshadow -m64 -DUSE_PTHREADS -DNDEBUG -O3 -DIS_64BIT -msse -msse3 -mpopcnt -DUSE_POPCNT -DUSE_AVX2 -mavx2 -DUSE_SSE41 -msse4.1 -DUSE_SSSE3 -mssse3 -DUSE_SSE2 -msse2 -flto -E -o errorTestPP.cpp nnue/evaluate_nnue.cpp

Then, I created the following bash script titled errorScript.sh which I placed in the src directory of Stockfish:

#!/bin/bash

! clang++ -Wall -Wcast-qual -fno-exceptions -std=c++17  -pedantic -Wextra -Wshadow -m64 -DUSE_PTHREADS -DNDEBUG -O3 -DIS_64BIT -msse -msse3 -mpopcnt -DUSE_POPCNT -DUSE_AVX2 -mavx2 -DUSE_SSE41 -msse4.1 -DUSE_SSSE3 -mssse3 -DUSE_SSE2 -msse2 -flto   -c -S -emit-llvm -o - -w errorTestPP.cpp | timeout 3s $HOME/llvm/build/bin/opt -enable-new-pm=0 -load $HOME/minotaur/build/minotaur.so -so -S -

After creduce, I got the following source file:

class a {
public:
  a(char *, const int & = int());
} b("");

Compiled using:
clang++ errorTestPP.cpp -S -emit-llvm -o errorTestPP.ll

Called supervec using:
$HOME/llvm/build/bin/opt -enable-new-pm=0 -load $HOME/minotaur/build/minotaur.so -so -S errorTestPP.ll
