I tried what you say with newly clean installed 64bit Windows 10 Pro
1909. But problem still happens.

Cygwin Package Information
Package              Version        Status
cygwin               3.1.5-1        OK
mintty               3.2.0-1        OK

And after number of trials and errors I add following definition of src_compile
function to zsh.cygport.

----------------------------------------------------------------------
src_compile() {
    cd ${S}
    cygautoreconf
    cd ${B}
    dash ${S}/configure --srcdir=${S}  --prefix=$(__host_prefix) --exec-prefix=$(__host_prefix) --localstatedir=$(__host_localstatedir) --sysconfdir=$(__host_sysconfdir)  --infodir=$(__host_prefix)/share/info --mandir=$(__host_prefix)/share/man -C --enable-function-subdirs --enable-gdbm --enable-multibyte --enable-pcre --enable-zsh-secure-free || error "configure failed"
    cygmake
}
----------------------------------------------------------------------

This is same as default definition except that dash is used to
interpret configure script. And with it build succeeded on 32bit
Cygwin console. So It seems I hit bug of bash that only happens under
very limited conditions.

And I'm wondering if I should investigate the problem further or
accept adding the function definition as a workaround.
