The example program is: program test implicit none
type c_struct type (g_struct), pointer :: g end type type g_struct type (p_struct), pointer :: p end type type p_struct type (region_struct), pointer :: r end type type region_struct type (p_struct) plot end type type (c_struct) curve(10) namelist / params / curve end program compiling with "gfortran test2.f90" hangs the compiler. I don't have a simple example but with other test programs I get the message: [gfortran] Compiling: test.f90 --> test_DBL.o gfortran: Internal error: Segmentation fault (program f951) Please submit a full bug report. See <http://gcc.gnu.org/bugs.html> for instructions. In any case, commenting out the namelist statement fixes the problem. Notice that this code is non-conforming since the "curve" variable has a pointer component but is also used in the namelist -- David PS: I am working on linux: lnx4103:~/bmad/bmad_dist/test> uname -a Linux lnx4103.lns.cornell.edu 2.6.18-194.11.1.el5 #1 SMP Tue Aug 10 16:39:28 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux -- Summary: gfortran internal compiler error Product: gcc Version: 4.5.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: david dot sagan at gmail dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45530
