So I've made a breakthrough. The memory corruption is due to both parts of
the CMOV optimization under OptPass2Jcc, not my Jcc addition (although it
might have unintentionally accentuated it). The first part sets p to a
dangling pointer, while the 2nd part is a little more complicated, but I'll
It turns out that it's invalid memory. Trying to call "ClassName" raises
an access violation (other aligns work fine). There's a dangling pointer
somewhere. I found one in the CMOV optimisation code, but that hasn't
fixed the crash.

Could you set a breakpoint on aggas.pas:721 (the call to doalign) with a
conditional on "tai_align_abstract(hp).aligntype=119"
