Could you set a breakpoint on aggas.pas:721 (the call to doalign) with a
conditional on "tai_align_abstract(hp).aligntype=119" and check what the actual
type of hp is? It could be that at some point a node gets its typ changed in an
invalid way?
aligntype should be either one of 2^[0..5], never something else...

This is where AddressSanitizer support would be *nice*.


Ceterum censeo b32079 esse sanandam.
