What do you mean by "fails" ?... Does its crash ? Or does the TP fails and the viewer keeps working ? There is no trace of a crash in the log you provide, and you did not provide the stack trace log file either (which would be there, in case of a crash)... I also need precise repro steps. |

Here's another log with the stack trace log, but it's 0 bytes. I'll tp to a hypergrid region from OSGrid, the viewer freezes just as things are starting to rez, then crashes. Linux Mint System Reports says CoolVLViewer-1.32.2/bin/cool_vl_viewer-bin could not be found.

I built the viewer from source and this time there's something in the stack trace. I hope this is what you need.

Apparently, the crash happens in glibc while locking a mutex from the mesh repository thread... It is extremely strange, and I'm not seeing it happening here... Maybe something to do with the fact that the mutex is also locked from a coroutine (the HTTP fetch completion call happening from within a coroutine of the mesh repository thread). Until I can understand what's going on, I'll revert the "threaded initial joint rigging data caching on mesh skin fetch" optimization which is responsible for this, and will published a fixed 1.32.2.54 later today. |

In today's v1.32.2.55 release I reintroduced the feature with an amended code: I simply removed the mutex since, the way the mesh fetching currently works, there should be no need for one (no risk for a race condition since the main thread code is only made aware that the skin info got successfully fetched after this mesh repository thread code is executed), and LL is not using one either in their code. But, just in case, I added a new "CacheMeshJointRiggingOnFetch" debug setting to allow disabling this code (by changing this setting to FALSE): let me know if you need to disable it to avoid crashes ! |

It still crashed on a hypergrid teleport. Disabling the code solves the problem. My log is attached, but the stack trace is empty.

I need the stack trace to diagnose the bug... |

It took a few tries before the compiled version created the stack trace, but here it is.
