[Bug fortran/45530] New: gfortran internal compiler error
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.

--- Comment #6 from david dot sagan at gmail dot com 2009-10-14 04:40 --- (In reply to comment #5) checking for correct version of mpfr.h... no That is correct error since mpfr cannot be used as you configured gcc so it is not the correct version :). No. This is not correct. See comment #3. It has nothing to do with the version of MPFR. The problem was that MPFR was built against a different version of GMP than the GMP version specified on the configure line.

[Bug bootstrap/40833] gcc configure problem with mpfr.h
--- Comment #4 from david dot sagan at gmail dot com 2009-07-23 15:32 --- It has nothing to do with the version number. Read the log file you included in your original post. You'll find Thanks for the information. As I see it, the problem here is that the error message from configure: checking for correct version of mpfr.h... no configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.2+. is wrong in this case. I would suggest that either 1) The error message be changed to reflect the fact that other things could be wrong or, preferably, 2) separate the mpfr test into pieces so accurate diagnostic messages can be generated. -- Again Thanks, David -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40833
