I translated the problem into C using f2c.  It becomes:

$ cat labugc.c
int main() {
  static float a[39*1024*1024];
}

$ gcc -O0 -o labugc.exe labugc.c
$ ./labugc
C:\cygwin\usr\people\billingd\labugc.exe (3372): *** MapViewOfFileEx(0x728, in_h 0x728) failed, Win32 error 6


Aha, I says.  Looks like stack overflow.  Google pointed me to an work around
gcc -Wl,--stack,200000000 -O0 -o labugc.exe labugc.c
