From the file name (tree-ssa-operands.c) I presume it has something to do with the new Static Single Assignment (SSA)  features in Gcc. More info on SSA can be found at http://gcc.gnu.org/projects/tree-ssa/ and http://en.wikipedia.org/wiki/Static_single_assignment_form

How to repeat:
Just run configure && make.

Looking the error message, seems to be a compiler bug:
default.c:440: internal compiler error: in get_indirect_ref_operands, at
tree-ssa-operands.c:1449

No it is not a compiler bug. The compiler aborted because the code in MySQL was invalid. If you look at the gcc source code you will see that explained in the comments.

No feedback was provided for this bug for over a month, so it is
being suspended automatically. If you are able to provide the

the status of the bug back to "Open".

sorry, but I don't see whether in the gcc source code it is explained in the comments.
Could you quote the relevant part here ?

Where what is explained? Have you done the compile with gcc4? You need to follow the steps I outline and also read my bug report in its entirety.

I was unable to reproduce this bug using 5.0.7 from bk
