Bug#1096811: hipblas: ftbfs with GCC-15

[Santiago Vila <sanvila@debian.org>]

close 1096811 6.4.3-2
thanks

Hello. I believe this bug ("FTBFS with GCC 15") is fixed in the above
version, so I'm closing it by hand now.

While we are at it, I noticed a very significant raise in the amount
of memory allocated while building the package, from 2GB in trixie to
14GB in current unstable (using machines with 2 CPUs).

Is this normal/expected?

Thanks.
