Bug#951704: ImportError: /lib/x86_64-linux-gnu/libjemalloc.so.2: cannot allocate memory in static TLS block

Package: libjemalloc2
Version: 5.2.1-1
Severity: important
Tags: patch

I cannot import the pyopenvdb module on Debian sid (amd64). It fails like this:

$ python3
Python 3.7.6 (default, Jan 19 2020, 22:34:52)
[GCC 9.2.1 20200117] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyopenvdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /lib/x86_64-linux-gnu/libjemalloc.so.2: cannot allocate
memory in static TLS block
>>>


Searching in the jemalloc bug report, I stumble upon:

* https://github.com/jemalloc/jemalloc/issues/937

Would it be possible to build jemalloc with:

--disable-initial-exec-tls

[...]
Disable the initial-exec TLS model for jemalloc's internal
thread-local storage (on those platforms that support explicit
settings). This can allow jemalloc to be dynamically loaded after
program startup (e.g. using dlopen). Note that in this case, there
will be two malloc implementations operating in the same process,
which will almost certainly result in confusing runtime crashes if
pointers leak from one implementation to the other.
