Add --param=ggc-min-expand=1 we get:
hash table checking failed: equal operator returns true for a pair of values
with a different hash value

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
I am going to assume this is the same bug when I reducing it but if it is not
then I will deal with it later.
