patch which solves the problem

this patch applies cleanly to libstdc++ 13.2 and 14.2 and also to head I
believe. 

It solves the problem. 

The code change is from here: 

https://github.com/oneapi-src/oneDPL/pull/1589/files

By one of the people on the TBB / oneDPL team.

it cannot be applied to TBB ( I did ask there) because the bug is in the
"glue/interface" code between libstdc++ and TBB and managed by libstdc++
