Perhaps you have low process memory limit? What do you have for 'ulimit -a'?

you can try 'ulimit -m unlimited' and see if that helps.

Alternatively - you can try manually compiling the failed sources with
a lower optimiation. Assuming you are using legacy build - you can
edit PETSC_ARCH/conf/petscvariables - and change the -O3 flag - and
then invoke 'make' in the src dirs where compile failed.
