The POSIX handler re-entered on SIGABRT (sysFatalError -> abort) and
truncated ge007.crash.log, so field crashes came back as bare abort
records with no faulting PC or registers. Guard against re-entry,
terminate directly with _exit(), and dump si_addr + the general register
set from the ucontext — a Deck crash now names the bad pointer on its
face.
Also documents D255 (new SIGSEGV in vtxstore's active-object walk during
a Facility firefight on the Deck; disassembly shows the fault is a
32-bit-zero-extended read of ObjectRecord.model, misnamed ChrRecord.
