	Known Issues

Compilers
- Intel Fortran and c/c++ Compilers, version 7.1 and 8.0
  problem: Upon compile, get error message like
  solution: use -i_dynamic flag when compiling.
- Intel Fortran and c/c++ Compilers, version 8.0
  problem: Get segmentation fault at runtime for large arrays
  solution: Place unlimit stacksize in your .cshrc file. See Intel bug report
- Intel Fortran Compiler, version 8.0
  problem: Get segmentation fault at runtime for large arrays, usually with Fortran 77 subroutines. Already set unlimit stacksize (see issue above).
  solution: Unknown. See Intel forum on this issue.
- Intel Fortran and c/c++ Compilers, version 8.0 using OpenMP
  problem: Get runtime error
  solution: At unix prompt, type setenv KMP_MONITOR_STACKSIZE 0
  During runtime, you may get the message
  This gives each child thread sufficient stack size.
  See Intel's OpenMP Environment Variables specifications.
- NAG Fortran 95 Compiler
  problem: The NAG Fortran compiler causes a "Segmentation Fault" after the program has run.
  solution: To avoid this, use the -unsharedf95 flag
Libraries
- NAG Libraries
  problem: NAG libraries are not linking correctly. For example,
  
  eady> cp /usr/local/NAG/asliR7/fll6420dbl/examples/source/a02aafe.f .
  
  Try Intel Fortran compiler:
  eady> /usr/local/intel/bin/ifort a02aafe.f -i_dynamic -L/usr/local/lib
  /tmp/ifort7CssNy.o(.text+0x142): In function `MAIN__':
  : undefined reference to `a02aaf_'
  
  Try Intel c compiler:
  eady> /usr/local/intel/bin/icc c02afce.c -I/usr/local/NAG/asliR7/cll6406da/include/ -L/usr/local/lib
  /tmp/iccLFGDW1.o(.text+0x112): In function `main':
  : undefined reference to `c02afc'
  
  Try NAG compiler:
  eady> f95 a02aafe.f -lnag
  Obsolescent: a02aafe.f: Fixed source form
  eady> a.out
  A02AAF Example Program Results
  output hangs
  
  Try gcc compiler:
  eady> gcc c02afce.c -lnagc -lm -lpthread -I/usr/local/NAG/asliR7/cll6406da/include/
  eady> a.out
  c02afc Example Program Results
  output hangs
  solution: unknown
Mathematical Software
- Mathematica 5
  problem: Links in notebooks cannot be activated
  solution:For Help notebooks, use the webpage instead.
  Otherwise, you will have to move around notebooks manually.
