[R] RCMD SHLIB == Couldn't reserve space for cygwin's heap, Win32 ?

[Jeff D. Hamann]

I've been trying to create/load/call a dll from R-1.8.1 on Windows without
much success. I've been able to at least load the library on FreeBSD
(1.8.1). I've been able to perform this before using DLL that weren't
created using RCMD SHLIB, but simply compiling under MS DevStudio.

C:\optflikam>

 Then from R, I've tried to simply load the library and R crashes and I
can't load the DLL. I keep getting the following error:

> dyn.load( "optflikam.dll" )
      5 [main] ? 4012 init_cheap: Couldn't reserve space for cygwin's heap,
Win32 error 487
c:\program files\r\rw1081\bin\Rterm.exe (4012): *** AllocationBase 0x0,
BaseAddress 0x61670000, RegionSize 0x1050000, State 0x10000

I thought it might have something to do with the compiler, so I looked at
the version of cygwin's gcc:

C:\optflikam>gcc --version
gcc (GCC) 3.3.1 (cygming special)

Is this the problem and has anyone else run into this? I've never seen this
meesage before.
