Bug: x86_64-w64-mingw32 REL_11_STABLE with features: UpdateStatisticsForTypeChange internal compiler error

Hi,

When trying compile PostgreSQL REL_11_STABLE using x86_64-w64-mingw32 using

/w/R-3.5._/postgres/configure --host=x86_64-w64-mingw32 --prefix=$PWD/build CFLAGS="-O -fno-omit-frame-pointer" --disable-rpath --enable-depend --enable-cassert --enable-debug --with-icu ICU_CFLAGS="-I/w/icu-61.1/icu4c/dist/include" ICU_LIBS="-L/w/icu-61.1/icu4c/dist/lib -licui18n -licuuc -licudata" --with-openssl --with-libxml --with-libxslt --with-tcl --with-python --with-perl --with-includes=/w/zlib-1.2.8-win32-x86_64/include:/w/openssl-1.0.2e-win32-x86_64/include:/w/libxml2-2.9.3-win32-x86_64/include/libxml2:/w/libxslt-1.1.28-win32-x86_64/include --with-libraries=/w/zlib-1.2.8-win32-x86_64/lib:/w/openssl-1.0.2e-win32-x86_64/lib:/w/libxml2-2.9.3-win32-x86_64/lib:/w/libxslt-1.1.28-win32-x86_64/lib

I am getting this error:

"
W:/R-3.5._/postgres/src/backend/commands/statscmds.c: In function 'UpdateStatisticsForTypeChange':
W:/R-3.5._/postgres/src/backend/commands/statscmds.c:435:1: internal compiler error: in based_loc_descr, at dwarf2out.c:14272
}
^
"

Note: I can build without any errors using just

/w/R-3.5._/postgres/configure --host=x86_64-w64-mingw32 --prefix=$PWD/build --disable-rpath --enable-depend --enable-debug

I examined "W:/R-3.5._/postgres/src/backend/commands/statscmds.c" at line 41.
The only thing I can think of is that maybe the code should include a "return void;"?

The following is my method and results.

I tried manually. . . .
