--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> 2012-01-22 17:45:27 UTC --- (In reply to comment #0) > Created attachment 26412 > taken from Damian Rouson's book , allocate seems to be the culprit > Source if from Damian Rouson from Sandia National Laboratories > It compiles properly with IBM xlf and Cray fortran compilers. > apparently the allocate statement > Allocate ( localprdct, source = rhs) > is the culprit I have to admit that I could not find that allocate statement. Neither in your attachment nor in the book's resources available at http://www.cambridge.org/rouson under "Resources available". However, I think it is the example chapter08/puppeteer_f2003. Using today's version of gfortran, it works. I can reproduce a segmentation fault using gfortran 4.7 of 2012-01-11. Could you try with a newer gfortran version? (We had some polymorphism-related fixes on the 13th, 16th and 18th of January.) * * * Otherwise, as far as I could see, all Fortran examples work except for - those using a FINAL subroutine (not yet implemented) - deferred-length strings as components of derived types (not yet implemented) - chapter07/strategy_surrogate_f2003: Segfaults in __timed_lorenz_module_MOD___copy_timed_lorenz_module_Timed_lorenz (not yet debugged) - chapter09: Fails at MOVE_ALLOC, see PR 51948 - chapter12/burgers_caf_v4: Issue with polymorphic coarrays, cf. PR 51947 [Disclaimer: That's with today's GCC 4.7 and with a patch applied for PR 51870 (alias PR48705) - I don't know whether it affects any result. In any case, puppeteer_f2003 also works without that patch.]
