ccls --version
ccls version 7.0.0 (Fedora 7.0.0-2.fc29)

Built using system clang/llvm (llvm-7.0.0-2.fc29.src.rpm); configured via cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -BRelWithDebInfo -DCMAKE_INSTALL_PREFIX=/usr -DSYSTEM_CLANG=On -DUSE_SHARED_LLVM=On -GNinja ..

I get a crash when indexing bolt, reproducible on the commandline via cls -index=/home/gicmo/Code/src/bolt:

From Getting started

You may use -DSYSTEM_CLANG=on if you have clang and llvm installed somewhere (can be a releases.llvm.org prebuilt archive, not necessarily installed via the system package manager). But caution is that you need to identify whether the clang library is compiled with -DLLVM_ENABLE_RTTI=on

Ups. Sorry, should have read that more carefully. Using cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -BRelWithDebInfo -DCMAKE_INSTALL_PREFIX=/usr -DSYSTEM_CLANG=On -DUSE_SHARED_LLVM=On -DLLVM_ENABLE_RTTI=On -GNinja .. fixed it.

Can you delete #0 #1 ... from the stack trace? It confuses github as it thinks this issue references #0 #1 ...
