R help - Feb 2002 - R crashes when .Fortran embeded function, is called twice in R

Hello,

I have few functions in fortran.. whose dll is generated and integrated with
C:\Pro..files\R\..library\...libs

Then I load the dll etc.. and call a R function, which inturn call the
function in dll, using .Fortran

Skeleton .Fortran call in R function:
	1. Set data (allocation ..)
	2. call the routine to evaluate (some simulation)
	3. unset data ( deallocation etc..)

Problem : 1st time I call, it works fine and gives the answer as expected.
If I call it second time without going out of R, then it fails and crashes
the R saying unknown error with Rgui.

FYI: I got calls to write/print which writes to the logfile instead to the
screen so no question of error due to printing, I think, I also checked with
allocation and deallocation sequence in setdata and unsetdata resp., it
should work as expected.

I will be very much thankful to you for helping me resolve this problem.

Thanks,
-Jag
