Bug#1031822: gcc-10: ICE in tsubst, at cp/pt.c:15310

[Roland Mas <lolando@debian.org>]

Package: gcc-10
Version: 10.2.1-6
Severity: important

Dear Maintainer,

As reported upstream in
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100102>, gcc 10.2 shows
internal compiler errors when used in conjuction with NVCC. A client
of mine uses gcc-10 and encounters the problem. Upgrading to version
10.4 fixes it for them, but they'd rather stick to stable releases.

Since the problem seems to be well understood upstream, with a clean
and minimal fix, would it be possible to include that fix in a
bullseye update?

Thanks,

Roland.
