Hi Louis,

My apologies for missing this when it was sent.

The problem here is that your docker image uses gdb 9.2, which doesn't handle dwarf5 info as generated by clang. You can read some discussion about this here:


The resolution of that discussion is that the package maintainer should be sure that clang defaults to a format the system debugger is capable of reading.

So you have two options: Make this build of clang default to dwarf4, or upgrade the docker installed copy of gdb to 10.2 or greater.

Not sure which is the best one for you. But in general this test works fine with newer copies of gdb and newer copies of clang, and disabling it probably isn't quite the right thing to do.
