Bug#1078336: code-saturne: FTBFS with GCC 14: error: assignment to 'const cs_real_t *' {aka 'const double *'} from incompatible pointer type 'float *'

[Andreas Beckmann]

Package: code-saturne
Version: 7.0.2+repack-1~exp1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

code-saturne/experimental started to FTBFS when GCC 14 was made the
default compiler:
