System Information
Kubuntu 18.10
NVidia 840m, 390.87 driver.

Blender Version

Worked: (optional)

Short description of error
Blender compiles without errors, but when I run it, it crashes immediately
with an error: : Error in dlsym(RTLD_NEXT, "pthread_create")
has been happening for couple of weeks.

Blender downloaded from buildbots work fine.

Exact steps for others to reproduce the error
Compile, run

It's probably this bug in jemalloc:
https://github.com/jemalloc/jemalloc/issues/907

Can you try this patch? I don't have Ubuntu 18.10 installed to test.

That is known issue, latest Ubuntu has buggy jemalloc package (ubuntu always have a buggy package it’d seem :( ). For now, please compile with WITH_MEM_JEMALLOC option disabled in CMake .
