I insert an function call in the IR, and causes the following error. and the error seems to happen on some cases. The attached file nest.c can be processes successfully and the nest-ddp.ll is the output file, but the nr__routines.c will fail. llvm-3.2-svn/lib/VMCore/DebugLoc.cpp:60: void llvm::DebugLoc::getScopeAndInlinedAt(llvm::MDNode*&, llvm::MDNode*&, const llvm::LLVMContext&) const: Assertion `unsigned(ScopeIdx) <Ctx.pImpl->ScopeRecords.size() && "Invalid ScopeIdx!"' failed. 0 opt 0x0000000000cde472 1 opt 0x0000000000cde147 2 libpthread.so.0 0x0000003faf60f500 3 libc.so.6 0x0000003faee328a5 gsignal + 53 4 libc.so.6 0x0000003faee34085 abort + 373 5 libc.so.6 0x0000003faee2ba1e 6 libc.so.6 0x0000003faee2bae0 __assert_perror_fail + 0 7 opt 0x0000000000b98f63 llvm::DebugLoc::getScopeAndInlinedAt(llvm::MDNode*&, llvm::MDNode*&, llvm::LLVMContext const&) const + 147 8 opt 0x0000000000b99166 llvm::DebugLoc::getAsMDNode(llvm::LLVMContext const&) const + 70 9 opt 0x0000000000c373ec llvm::Instruction::getMetadataImpl(unsigned int) const + 52 10 opt 0x0000000000c36f93 llvm::Instruction::getMetadataImpl(llvm::StringRef) const + 73 11 libLDDProfileInstrument.so 0x00007f4fe146a14d 12 libLDDProfileInstrument.so 0x00007f4fe14661aa 13 libLDDProfileInstrument.so 0x00007f4fe1465231 14 libLDDProfileInstrument.so 0x00007f4fe14660bc 15 opt 0x0000000000c441d0 llvm::MPPassManager::runOnModule(llvm::Module&) + 456 16 opt 0x0000000000c446f5 llvm::PassManagerImpl::run(llvm::Module&) + 125 17 opt 0x0000000000c448ad llvm::PassManager::run(llvm::Module&) + 39 18 opt 0x00000000006acebb main + 5540 19 libc.so.6 0x0000003faee1ecdd __libc_start_main + 253 20 opt 0x000000000069cce9 -------------- next part -------------- An HTML attachment was scrubbed...
