Dear Masayoshi,

I encountered several times problems as yours: Abinit crashes when some
agressive optimization levels are chosen, especially with pgui compiler.
It's generally complicated to find the source of the problem (at which line
Abinit crashes).
I generally find ifort compiler more stable; did you test v9.1 instead of
v8.1 ?

Reading the list of your crashed tests, I'm pleased to see that none of the
PAW tests... except v5#t09 but it is testing the "conducti" PAW feature...
v5#t10 is supposed to use v5#09 output in the conducti post-processor...

You could have a look at the tests/v?/README files in order to find what
problematic tests have in common... and put "-O2" to selected directories.

"Asta la vista, baby",
Marc
