testcase
The attached code initializes the data array wrong when using enumerations.
If the code is changed to use integers it works.
It also works if during initialization a printf is done.
The code aborts if compiled with: gcc -O3 tst.c -o tst; ./tst
The code works if compiled with: gcc -O3 tst.c -o tst -DPRINT; ./tst
De code also works if compiled with -O2.
