A problem while building xapian-bindindgs for python 3.6 on i686

[Lemures Lemniscati]

Hi!

I'm trying to build xapian-core and xapian-bindings 1.4.18 with cygport
files:
https://github.com/cygwin-lem/xapian-core-cygport/tree/n_1.4.18-0.1
https://github.com/cygwin-lem/xapian-bindings-cygport/tree/n_1.4.18-0.1

But, on i686, I've failed to build xapian-bindings for python 3.6.


----

I've built xapian-core 1.4.18 successfully on x86_64 and on i686.
And on x86_64, I've succefully built xapian-bindings.


On i686, I've succefully built xapian-bindings for python 3.7 and 3.8, 
but failed to build xapian-bindings for python 3.6 with a message
'*** stack smashing detected ***: terminated'.

https://github.com/cygwin-lem/xapian-bindings-cygport/blob/n_1.4.18-0.1_log/xapian-bindings-1.4.18-0.1.i686/log/xapian-bindings-1.4.18-0.1-compile.log#L1618


I've no idea what is wrong.
Please, help me.
