Can you open a new bugreport please? It's very likely a different
reason than this one.
After a lot of fiddling about, please

OK, new investigation show that using the smaller testcase firebird2-nav.cc
shows the inliner is misbehaving.
before inlining (*041t.profile):

They do all have the (ab) next to them, I was just indicating that they all
occurred in a PHI together, and hence needed to be coalesced. I should have
been more precise.
Well, _t_3 definately does have the (ab) flag,

Looking at the original testcase, the complaint is that _t_8232 and _t_3 are
both used in the PHI definition of _t_7. (using mainline

I have a fairly small C++ testcase for what appears to be the same issue:

I think that issue is actually different as the SSA inliner came in after this
bug was filed so I filed this with a reduced testcase as PR

Looking at the original testcase, the complaint is that _t_8232 and _t_3 are
both used in the PHI definition of _t_7. (using mainline from march 5th)
ie, _t_7(ab) = PHI , _t_8232, ... , _t_3, ...

-fno-tree-fre makes the test case compile, which is further indication FRE is
the problem.

I can reproduce this ICE but it is very hard to see where the problem is with
such a long testcase.
