[Bug tree-optimization/19736] New: ICE with type mismatch between SSA_NAME and its symbol

[janis at gcc dot gnu dot org]

Today's GCC mainline ICEs building 176.gcc from SPEC CPU2000 on
powerpc64-unknown-linux-gnu with "-O1 -g" and either -m32 or -m64:
                                                                                
sdbout.c:1026: error: Type mismatch between an SSA_NAME and its symbol.
sdbout.c:1026: error: Missing definition

specmake: *** [sdbout.o] Error 1
                                                                                
The "sdbout.c:1026" here is in the benchmark program being compiled.
                                                                                
I'll try to provide a minimized testcase tomorrow.
