Segmentation fault on indexing

[L0ric0]

Observed behavior

when indexing files a Segmentation fault is observed
unfortunatly i am unable to provide the source and don't have the time at the moment to reduce to a minimal program
the error ocures while beeing someware in the https://github.com/boostorg/boost subtree of the project and using around 24.1 GB of total RAM + swap
when restarting the indexing there is progress observed when using the cache.

init args:
{
  "cache": {
    "directory": "/home/lsteinert/.cache/ccls/"
  },
  "highlight": {
    "lsRanges" : true
  }
}

Thread 9 "indexer4" received signal SIGSEGV, Segmentation fault.

Expected behavior

indexing without a Segmentation fault

Steps to reproduce

• just indexing the project

System information

• ccls version (git describe --tags --long): 0.20190823.5-20-g24dd3bd4
• clang version:

clang version 10.0.0 (https://github.com/llvm/llvm-project.git d32170dbd5b0d54436537b6b75beaf44324e0c28)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /home/lsteinert/usr/bin

• OS: Linux emil 4.19.0-8-amd64 Thanks for your hard work #1 SMP Debian 4.19.98-1 (2020-01-26) x86_64 GNU/Linux
• Editor: none just ccls -index
• Language client (and version): see editor

This is a clang stack overflow which can't be protected by llvm::CrashRecoveryContext::RunSafely

Please try debugging the issue (https://github.com/MaskRay/ccls/wiki/Debugging) and at least report which file can cause problems.

Assuming this is good with Clang 10 or 11. Closing.
