Mostly I recommend compiling clang without assertions. I don't know what actually causes the assertions but I believe the condition generally is benign if ignored.

Your clang is still compiled with assertions. This is something of a known issue. We should probably report it to the clang maintainers. I think you have to blow away your build directory and compile llvm/clang again and explicitly turning off assertions.

Actaully, I did redownloaded the llvm and clang and recmopiled them all again.

And my current llvm-config --assertion-mode tells me "OFF"

casch-at commented 6 years ago

Closing this issue, as it is very likely a clang problem!

Shooooooooo commented 5 years ago

Hi, sorry for bring this back up. I am also experiencing this issue on CentOS. (6.7) One interesting fact is that: if I start rdm with "--enable-compiler-manager", I got this crash. But if I put "--enable-compiler-manager" flag to .rdmrc, I no longer have this crash. I understand the previous reporter does not even have this flag in his config, but I just want to put this discovery here. Do we have a description of what this assertion failure complaining about?
