            Bug ID: 71953
           Summary: ICE using sanitizers with PCH
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: sanitizer
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

This happens when I try to enable asan and/or ubsan in the libstdc++ testsuite.

Possibly component should be pch, but I want someone to actually look at it ;)

I can't reproduce it with preprocessed source, because I get an invalid-pch
error unless it's done in the build tree when the PCH file is present.

With suitable values of SRCDIR, OBJDIR and TARGET:

echo | $OBJDIR/gcc/xg++ -B$OBJDIR/gcc -fsanitize=address -g -O -c -nostdinc++
-I $OBJDIR/$TARGET/libstdc++-v3/include/$TARGET  -include bits/stdc++.h -x c++
