Using clang 11.0.1 (in a toolchain generated with crosstool-ng): http://cdn.unrealengine.com/Toolchain_Linux/native-linux-v19_clang-11.0.1-centos7.tar.gz crashes when combining the arguments `-emit-obj --compress-debug-sections -debug-info-kind=limited`. If any of them are removed it works fine.
```
clang -cc1 -emit-obj --compress-debug-sections -debug-info-kind=limited -o apa.o -x c apa.c -v
clang -cc1 version 11.0.1 based upon LLVM 11.0.1 default target x86_64-unknown-linux-gnu

Segmentation fault (core dumped)
```
The C file is this:
```c
int main()
{
return 0;
}
```
Using the same command line with clang 11.1.0 works fine although that one is admittedly not from a crosstool toolchain.
