With the current GCC 4.7 I get for the original example (comment 0, attachment
26126) but also for Steve's reduced test case in comment 3 the error:
integer_ptr => symbol_ptr
1
Error: Pointer assignment target is neither TARGET nor POINTER at (1)
[Cf. comment 2, PR 48887]
I believe the error message is correct due to (F2008, 16.5.1.6 Construct
association):
"If the selector has the POINTER attribute, it shall be associated; the
associate name is associated with the target of the pointer and does not have
the POINTER attribute."
And due to the error message, the code part which ICEs cannot be reached.
Dan: You wrote: "Compiles with fort 12.1, nagfor has a different problem."
Do you believe the code is valid, if so, why doesn't 16.5.1.6 apply? If it
applies, can you construct a valid example which still fails?
Dan, Stave: If possible, please also update your GCC to 2011-12-11 or newer -
at least if you use OOP/polymorphism features. (You might be able to get a
newer binary from http://gcc.gnu.org/wiki/GFortranBinaries )
