This must have been introduced in last few days when our CI has been out of order.
Last known good SHA `6ef80e147c63ad84cd616cb4d664b1caf0dbc4bf`, first known 'bad' SHA `6574918875401825fb3a13f049740d40ba496853`.
Environment: RHEL8 or SLES15sp7
Purpose: build Gromacs with Spack
Details: Spack first builds CMake with indicated compiler (clang/clang++) then using this CMake it configures the Gromacs build.
Regression: a segfault while configuring the `muparser` part of Gromacs:
On RHEL8:
```

07:41:14 271 CMake step for muparser failed: Segmentation fault
```
On SLES15sp7:
```

```
Does not happen on more recent (RHEL9, RHEL10) systems with a more modern glibc and libstdc++.
