[PATCH] libstdc++: Fixing Error: invalid type argument of unary '*' (have 'int')

[PATCH] libstdc++: Fixing Error: invalid type argument of unary '*' (have 'int')

[Seija Kijin]

Had an error compiling tiny-cuda-nn using gcc 12.1. With this minor
patch, I recompiled and the build succeeded.

No behavioral change.

This looks like a bug in the cuda compiler then. The libstdc++ code is
correct.

N.B. libstdc++ patches need to be CC'd to the libstdc++ list, or they
won't get reviewed.
