 Reporter:  dmyzl      |      Owner:  pramsey
     Type:  defect     |     Status:  new
 Priority:  medium     |  Milestone:  PostGIS 3.5.4
Component:  postgis    |    Version:  3.5.x
 Keywords:  ST_Reskew  |
-----------------------+---------------------------
 The following SQL causes the server to crash when run on an ARM machine.
 Interestingly, if the first coordinate of the point consists of 308 nines,
 it returns a proper error. But when the number of nines reaches 309 or
 more, the server crashes:
