Problem with scanf and float under Cygwin on Windows ME Operating System

I have been having a problem with scanf and floating point numbers in Cygwin
on a WindowsME machine.  I have run this same program under Linux and have
had no problems with it. As soon as the float number is entered the program
terminates abnormally.  The error message says there is a "Segmentation
Fault : Probably a corrupted stack." The program I used is below, followed
by the core dump file produced when the program is run. Note: I have not had
any problems with scanf using strings or integers, only floating point
numbers.  I saw others mention this problem in the Cygwin mailing list
archive, and someone reported that this bug had been fixed. However, I have
the latest version of Cygwin installed, with the gcc that is included with
the installation.  Anyone have any suggestions?

#include <stdio.h>

int main(void)
float a = 1;

printf("number a is %f \n",a);
printf("new number is %f \n",a);
