            Bug ID: 91991
           Summary: ICE in linemap_macro_map_lookup when LTO-building
                    SQLite after r275402
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: preprocessor

            Target: x86_64-linux

since r275402 (git mirror commit 8bc9c0bbee9), attempts to build
SQLite with LTO result in an ICE:

In order to reproduce, download sqlite from
https://sqlite.org/download.html (I used
sqlite-snapshot-201909271633.tar.gz), build trunk, set PATH to use the
built trunk compiler, configure with

./configure CFLAGS="-O3 -flto=64" CXXFLAGS="-O3 -flto=64"

and run make.
