The following ASTImporterTest reproduces the assert:
TEST_P(ASTImporterOptionSpecificTestBase, SourceLocationDifferentTU) {
TranslationUnitDecl *ToTU = getToTuDecl("void f1();", Lang_CXX11);
Decl *FromTU = getTuDecl("void f2();", Lang_CXX11, "input.cc");
auto *ToF1 = FirstDeclMatcher<FunctionDecl>().match(ToTU, functionDecl());
auto *FromF2 = FirstDeclMatcher<FunctionDecl>().match(FromTU,
functionDecl());
auto *ToF2 = Import(FromF2, Lang_CXX11);
bool Before1 =
ToTU->getASTContext().getSourceManager().isBeforeInTranslationUnit(ToF1->getLocation(),
ToF2->getLocation());
bool Before2 =
ToTU->getASTContext().getSourceManager().isBeforeInTranslationUnit(ToF2->getLocation(),
ToF1->getLocation());
EXPECT_NE(Before1, Before2);
}
