static TLS exhausted on ppc64le

[Dan Horák <dan at danny dot cz>]

Hi,

I would like to open a problem we have already met twice in Fedora. the
symptom is

"/lib64/libgomp.so.1: cannot allocate memory in static TLS block"

usually when loading a lot of libraries/modules into a Python
application. It happened on ppc64le and also on aarch64 systems.

We have 2 reports in Fedora bugzilla about with more details.
https://bugzilla.redhat.com/show_bug.cgi?id=1722181
https://bugzilla.redhat.com/show_bug.cgi?id=1738752

We have already discussed that briefly with Florian and other members of
the Red Hat toolchain team, but outcome was in form of a recommendation
to reduce the usage of "static TLS" objects in the individual libraries.
But the open question still is - is there a fix for the TLS space
exhaustion? I believe it can easily become a more serious problem soon.


	Thanks,

		Dan
