P.p.s I just noticed the issue does not occur for GCC/4.9.2 but does occur for
GCC/4.9.3-2.25. This is consistent.

P.s. This issue does NOT occur if using g++ from a GCC built outside of the
Easybuild framework.

Subject: [easybuild] install dir on gpfs
Has anyone installed easybuild on GPFS, not NFS? We just migrated our easybuild
installation to GPFS, and now when we use an Easybuild-built compiler to build
software (on GPFS), the “configure” step fails when tests the compiler to
create an executable, and tests whether the executable works. You can see the
issue here:
xyz@bnbmgmt2:~/tmp$ g++ hello.cpp ; ./a.out
-bash: ./a.out: cannot execute binary file
xyz@bnbmgmt2:~/tmp$ ./a.out # it work a couple seconds later
Hello World!heywood@bnbmgmt2:~/tmp$
xyz@bnbmgmt2:~/tmp$
xyz@bnbmgmt2:~/tmp$ g++ hello.cpp ; file a.out
a.out: data
xyz@bnbmgmt2:~/tmp$ file a.out # gives expected output a couple seconds later
a.out: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked
(uses shared libs), for GNU/Linux 2.6.18, not stripped
