The issue is transitive relations are being registered in an unbounded way.
SymCount_369 = SymCount_368 + 1;
SymCount_370 = SymCount_369 + 1;
SymCount_371 = SymCount_370 + 1;
_370 > _369, and _369 is > _3

The problem is reproducible with -O1 and above. To confirm it's not infinite
recursion I let the process run for about an hour before killing it. Memory
consumption seems to slowly but steadily increase as

The basic block being analyzed is bb 2 in clang::clangd::stdlib::initialize().
What's unusual about it is that it's a sequence of 2464 assignments like so:
:
SymCount_21 = 0;
SymCount_22 = SymCount_21 + 1;

Unreduced test case.
The attached translation unit reproduces the infinite loop.
