Hi, since two days the GMT.jl CI tests start to fail (well, they don’t even start) with an cryptic error message saying:

```julia
ERROR: LoadError: LoadError: could not load library "/home/runner/gmt-install-dir/lib/libgmt.so"
/opt/hostedtoolcache/julia/1.6.4/x64/bin/../lib/julia/libstdc++.so.6: cannot allocate memory in static TLS block

```

Googling for `cannot allocate memory in static TLS block` brings several other cases and suggestions to use `LD_PRELOAD` but an attempt using it in the module definition file made no effect.

The tests run on Ubuntu 20.04 and that has not changed. Anyone has an idea on what that means and possible solutions?

Thanks.
