So even though the hash table wasn't the dbus hash table, omitting the dbus code somehow avoids the problem? Odd. All that sounds to me like we ought to dig down into the core file and figure out what happened, since the issue is likely to remain present otherwise and it seems somewhat difficult to track down and reproduce. The other odd thing is that 0xc000000018000000. That looks like a GC-marked pseudovector header, but I've checked and can't find anything that would generate PVEC_COMPILEDs of length 0, which would be a severe bug. Can you find out which hash table lives at 0x7ffff19a41a8? I'd suggest something like "find &globals,&globals+1,0x7ffff19a41ad" to get the offset in globals, if it is a global variable, then looking it up with "ptype/o globals". (If you don't have the time, I'd be happy to look at the core file myself, if we can arrange that).
