ROOT 6.24 debug build failed on ppc64le #9297
Description
Currently we are using ROOT 6.22 for CMS offline SW (CMSSW). It works great on all our supported archs e.g. amd64, ppc64le, aarch64, slc7/cc8 using gcc 9.3 10.3, 11.2. Now we are trying to move to ROOT 6.24 for CMS Offline Software ( CMSSW) but for
OS: slc7
Compiler: GCC 9.3
ARCH: ppc64le
when we try to load CMSSW dictionaries then pyROOT fails with error see full log

In order to debug this issue when I tried to build root in debug mode -DCMAKE_BUILD_TYPE=Debug -DLLVM_BUILD_TYPE=Debug then root failed to build with error see full log

Any idea what could be wrong here ?
