The same sources work fine on other architectures like `amd64` or `arm64`.
Please find the Debian unstable build log here: https://buildd.debian.org/status/logs.php?pkg=rocblas&ver=6.4.4-1&arch=ppc64el
Please find the Ubuntu resolute build log here: https://launchpad.net/ubuntu/+source/rocblas/6.4.4-1/+build/31463786
Here is the backtrace:

clang++-21: error: clang frontend command failed due to signal (use -v to see invocation)
Ubuntu clang version 21.1.2 (2ubuntu6)

```
Please find a tarball [1] containing a subset of the sources (generated by `strace`ing the failing process), that leads to a fast and consistent reproducer using the following procedure.
Please make sure to run that in an isolated environment. 1) you can never trust a tarball from the Internet and 2) this will make a mess of the machine, writing to many system-owned paths.
```
