vcregress.bat check triggered Heap error in the Debug version of win32 build

When I build the debug version of PostgreSQL (latest code), I found that I always failed to
run the vcregress.bat check. It always pops up the following error.
The release version can pass the test without any error.

Anyone met such error?

Here is my config.pl used in the build:

# Configuration arguments for vcbuild.
use strict;
use warnings;
our $config = {
asserts=>1, # --enable-cassert
# integer_datetimes=>1, # --enable-integer-datetimes - on is now default

};
1;

Any help is appreciated.
