Hi, all. Before I do any more clang hacking, I thought I'd look at getting clang to pass all of its current tests. It's failing most of the rewriter tests with a segfault. This is on a 32-bit Ubuntu Gutsy system, using gcc version 4.1.3. I'm over my head here, but I expect someone else might be able to help.
The backtraces indicate that the segfaults are all happening in the same bit of code. Here's the first one: Command: clang -rewrite-test Rewriter/objc-encoding-bug-1.m | clang Output: clang(_ZN40_GLOBAL__N_Signals.cpp_00000000_4112E74C15PrintStackTraceEv+0x22)[0x851c410] clang(_ZN40_GLOBAL__N_Signals.cpp_00000000_4112E74C13SignalHandlerEi+0x112)[0x851c542] [0xffffe420] clang(_ZN5clang12HeaderSearch11getFileInfoEPKNS_9FileEntryE+0x12)[0x8402b42] clang(_ZN5clang12HeaderSearch16getFileDirFlavorEPKNS_9FileEntryE+0x18)[0x82e6c14] clang(_ZN5clang4Sema16MergeTypeDefDeclEPNS_11TypedefDeclEPNS_10ScopedDeclE+0x1a8)[0x837eb5e] clang(_ZN5clang4Sema15ActOnDeclaratorEPNS_5ScopeERNS_10DeclaratorEPv+0x280)[0x83801d6] clang(_ZN5clang6Parser43ParseInitDeclaratorListAfterFirstDeclaratorERNS_10DeclaratorE+0xa1)[0x83ef585] clang(_ZN5clang6Parser22ParseSimpleDeclarationEj+0x108)[0x83ef916] clang(_ZN5clang6Parser16ParseDeclarationEj+0x44)[0x83ef998] clang(_ZN5clang6Parser24ParseExternalDeclarationEv+0x250)[0x83ea4c4] clang(_ZN5clang6Parser17ParseTopLevelDeclERPv+0x3d)[0x83ea51f] clang(_ZN5clang8ParseASTERNS_12PreprocessorEPNS_11ASTConsumerEb+0x18d)[0x8373d61] clang[0x82eb930] clang(main+0x5ab)[0x82ec279] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe0)[0x4017f050] clang[0x82c4fc1] Segmentation fault (core dumped) It's the second clang process that's core dumping. gdb says that OldDeclFile in Sema::MergeTypeDefDecl is null. I'm happy to answer any questions, but I may be slow in responding due to time constraints.
