Bug ID: 24318 Summary: Segmentation fault when using nested templated typedefs Product: clang Version: 3.6 Hardware: PC OS: Linux Status: NEW Severity: normal Priority: P Component: C++ Assignee: unassignedclangb...@nondot.org Reporter: gereon.kre...@cs.rwth-aachen.de CC: dgre...@apple.com, llvmbugs@cs.uiuc.edu Classification: Unclassified Created attachment 14674 --> https://llvm.org/bugs/attachment.cgi?id=14674&action=edit Source code Some of our code makes clang 3.6.2-1 (Arch Linux) crash. Based on our code, I crafted a very small example demonstrating this bug. Basically, we have a templated class A with a nested class B that is also templated. Now, we have another templated class C that defines a typedef for A<T>::B<T>. Finally, we try to use this typedef in the main function. Clang bails out on this: $ clang++ clangcrash.cpp clang: error: unable to execute command: Segmentation fault (core dumped) clang: error: clang frontend command failed due to signal (use -v to see invocation) clang version 3.6.2 (tags/RELEASE_362/final) Target: x86_64-unknown-linux-gnu Thread model: posix clang: note: diagnostic msg: PLEASE submit a bug report to http://llvm.org/bugs/ and include the crash backtrace, preprocessed source, and associated run script. clang: note: diagnostic msg: ******************** PLEASE ATTACH THE FOLLOWING FILES TO THE BUG REPORT: Preprocessed source(s) and associated run script(s) are located at: clang: note: diagnostic msg: /tmp/clangcrash-21862e.cpp clang: note: diagnostic msg: /tmp/clangcrash-21862e.sh clang: note: diagnostic msg: ******************** Attached, you find the example. -- You are receiving this mail because: You are on the CC list for the bug.
