Bug #: 14589
Summary: Assertion `Loc.isValid() && "point of instantiation
must be valid!"' failed
Product: clang
Version: 3.2
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Clang built from recent release_32 branch (rev. 169987) aborts with a failed
assertion for me:
> $ cat test.cc
> template<typename> struct S1 {};
> struct S2 {
> S2(int = 0);
> S2(S1<void>);
> };
> template<typename> void f1() { new S2(); }
> void f2() { f1<void>(); }
> $ /data/clang/release_32/inst/bin/clang -cc1 test.cc
> clang:
> /data/clang/release_32/src/tools/clang/lib/Sema/../../include/clang/AST/DeclTemplate.h:1446:

> clang::ClassTemplateSpecializationDecl::setPointOfInstantiation(clang::SourceLocation):
> Assertion `Loc.isValid() && "point of instantiation must be valid!"' failed.
