This error occurred for me with gcc-9.1.0 but not with gcc-8.3.0.
I was able to circumvent this bug for the time being. The bug appears to have to do with enabling the `elbeem` USE flag. RedHat Bugzilla Bug 1674700 (https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=1674700) seems to have more information. It directs me to a section of GNU's article on porting to gcc9 (https://gcc.gnu.org/gcc-9/porting_to.html#ompdatasharing). The specific error seems to have to do with OpenMP: it now requires additional declarations in #pragma blocks, but I am not well versed enough in C to understand what this means. Nonetheless, I am fluent enough in C to track down the error to elbeem's solver_main.cpp file. Compiling the file manually, we find the offending #pragma blocks to be on lines 381, 1126, and 1164. With some effort, I created a patch file. I was able to compile `media-gfx/blender-2.79b-r1` with the `elbeem` USE flag, though I do not know whether or not I inadvertently created more errors.

*** Bug 685194 has been marked as a duplicate of this bug. ***
Fixed upstream in https://developer.blender.org/rBd780409156e838e366f4da5126e6aeab44174d62 ? Bump please?

Gcc 9.2.0 recently went stable on amd64, so I expect more people are now exposed to this bug (as I am). We've got a patch (two actually), let's commit it ?
