two comments: this looks like a race condition somewhere. if I wait a couple of seconds before moving the newly reattached device, I don't seem to get crashes. I get *a lot* of unrelated memory issues when I e.g. zap the server. DeletePassiveGrabFromList() triggers a SIGABRT during xreallocarray even though all the input data looks correct so we probably have memory corruption elsewhere. This particular segfault is caused by a list->next pointer being NULL, simply said this cannot happen without unrelated memory corruption. Created attachment 1211191 [details]
valgrind of xserver master
still present on xserver master. valgrind output from xserver master (5dcb0666b) when calling create-master and reattach, followed by some mouse movement (no crash) and a server zap.
just attaching this here so I don't lose it.

Description of problem: I encountered this while trying to set up multiple input devices for use with a pair-programming setup. > xinput create-master "Second Seat" > xinput reattach "HID 0430:0100" "Second Seat pointer" After this, Xorg segfaults once I move the reattached mouse.
