Just had another one, apparently at the same location. |

And another, this time with CI #4835. |

And another, this time with CI #4900. If I understand the logs correctly, they show that the segfault always occurs in function sh_delentry(), by attempting to store R6 at [R5,#36] when R5 is 0. Isn't this just a classic null pointer problem? |

Certainly that sounds possible Dave. The new libcurl has changed shape slightly so we need to wait for something new to show up before I can look again. I think it's inside the CURL code associated with cleaning up socket filehandles from its hash table. |

https://github.com/curl/curl/issues/3995 The lowest 14 levels of the call tree are identical. So other people are seeing the same problem in completely different contexts. But, from your comments, I see you're ahead of me! |

I haven't seen this crash in a long time now. Can we assume that it's been fixed by some change in cURL? |

I haven't seen an ABEND in years, so I'm going to assume it's fixed. |
