TMPL_TYPE_LITERAL has non-zero bytes in its data union

[Geaaru]

Hi,

in our dev environment now with development version from upstream tree
3.0.x I see this error:

CONSISTENCY CHECK FAILED src/main/map.c[1529]: TMPL_TYPE_LITERAL has
non-zero bytes in its data union

This is an error is related to some issue on linking of the binary
between mismatched versioning for same libraries or it's related to a
wrong configuration?
In Sabayon we have upgraded to glibc-2.29 so I'm not sure if could be
related to some issues of compatibility or whatever.

Thanks in advance for any clarification
