NAMD-2.14-intel-2020a-mpi.eb fails to build on my Ubuntu 20.04 on a Coffee Lake 8700K when building a bundled Charm++ as shown in the log above with multiple instances of errors like this:
../bin/charmc -optimize -production -O2 -xHost -ftz -fp-speculation=safe -fp-model source -fPIC -DMPICH_IGNORE_CXX_SEEK -fpermissive -I. -o ../lib/libmemory-gnu-paranoid.a -DCMK_MEMORY_BUILD_PARANOID -touch-on-failure libmemory-gnu-paranoid.o

The declaration of mremap in the system header is:
extern void *mremap (void *__addr, size_t __old_len, size_t __new_len,
int __flags, ...) __THROW;I don't seem to find which PR if any that introduced this easyconfig so I can't see any previous test reports for systems like mine - all I can find is the adding commit 797ea75.
NAMD-2.14-foss-2020a-mpi.eb and NAMD-2.14-foss-2019b-mpi.eb build fine.
