CYGWIN控制台中出现奇数错误，“检测到cygheap基本不匹配”

Question

我用C语言编写了一个简单的应用程序（用于测试）-Windows 10上的CYGWIN（x86_64-pc-cygwin）上的GCC 9.3.0，并且运行良好。但是在1-2天前，Windows 10已更新（功能更新1909（2））。我不知道更新是下一个错误的原因，但是现在应用程序有时可以工作，但更多情况下它会失败并显示错误：

$ ./xxx.exe
      0 [main] xxx (7152) D:\prj\xxx\xxx.exe: *** fatal error - cygheap base mismatch detected - 0x180343408/0x1093408.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.

[在Cygwin控制台（bash）-Cygwin.bat中运行时会发生。我在bash环境中看不到奇怪的事情。 但是在PowerShell中运行总是正常（cygwin1.dll与应用程序位于同一文件夹中。）> Cygwin的bash中的ldd xxx.exe显示：

我使用以下方式构建应用程序：

...
CC = d:/apps/cygwin/gcc
LIBS := libFreeImage.a
...
$(EXE): $(OBJECTS) $(HEADERS)
    $(CC) $(CFLAGS) $(OBJECTS) -o $(EXE) $(LIBS)
这里怎么了？哪里有错误？

rm /cygdrive/d/prj/xxx/cyg*.dll，问题可能会消失。
