Following Pierre-Matthieu's instruction, I compiled abinis and abinip
with 5.2.2 on a 64-bit machine using "mpxlf90_r -q64" to replace
mpxlf90. A tricky thing is that test jobs always crashes when it is
compiled with default optimizations flags giving a "segmentation fault"
error. I had to use -O0 as  Pierre-Matthieu suggested. Now the code is
working.
