[R] Rgui Application error help!

[Yunming Mu]

Dear R-Users

I was trying to call a Fortran 77 subroutine from R 2.0.0 in Windows
XP. I have  Rtools, Perl and MinGW as described  in
http://www.murdoch-sutherland.com/Rtools/ with path sets.
When I use C:\R\rw2000\bin>Rcmd SHLIB test.f,
a test.dll is created without error and located in that directory, but when
I call the subroutine in R 2.0.0, R crashed and I got an error message
as follows:

Rgui.exe-Application error
the instruction at "0x5ad71531" referenced memory at "0x00000014".
The memory could not be "read".

I believe that the Fortran 77 code is causing no problem. Also,
please note that the same Fortran77 subroutine was called successfully
in Unix version of R. (test.so was created accordingly). I am
wondering whether R for Windows call Fortran subroutine in a different
way than R for Unix? Any insight would be highly appreciated!

Thanks!
