Changing the third line to
  INTEGER, POINTER :: P ! no initialization

seemingly exposes memory corruption inside the compiler:
[tobi@marktplatz src]$ gcc/build/gcc/f951 t2.f90
 a

Execution times (seconds)
 final                 :   0.00 ( 0%) usr   0.00 ( 0%) sys   0.01 (12%) wall
 TOTAL                 :   0.03             0.00             0.08
Extra diagnostic checks enabled; compiler may run slowly.
Configure with --disable-checking to disable checks.
[tobi@marktplatz src]$ gcc/build/gcc/f951 < t2.f90
Warning: Reading file  as free form

[tobi@marktplatz src]$

i.e. only when reading from stdin the compiler segfaults. I'll attach valgrind
output for both cases.
