Compiling with gcc 15

Dear all,

I have received a bug report seemingly related to the compatibility of
orthanc-mysql with gcc 15 in Debian trixie/sid [1].

However, I am unable to reproduce this error on Debian unstable by
manualling compiling the package from source using the following
invocation of CMake (same invocation as in the "debian/rules" file):

$ CC=gcc-15 CXX=g++-15 cmake ../MySQL/ [...]

Please could someone explain me how to reproduce this issue?

I guess this results from different versions of the dependencies
installed on my system, so I should provide the gcc/g++ version to
"pbuilder" or "gbp buildpackage", but I cannot find how to do this.

Thanks in advance!
Sébastien-

PS: The same bug was introduced against orthanc-postgresql [2].
