Description Pascal Jäger 2021-11-03 21:56:52 UTC
When I emerge firefox with 
sysctl kernel.yama.ptrace_scope=1 
the build stalls at a random point. In the build log I see several massages saying 
Unable to trace children due to YAMA ptrace_scope=1
I do not know if this has something to do with it, though.

Reproducible: Always

Steps to Reproduce:
1.sysctl kernel.yama.ptrace_scope=1 
2. emerge firefox
Actual Results:  
Firefox build stalls

Expected Results:  
Firefox build is succesful

    profiles: mask newer sandbox versions w/ ptrace issues
    
    Masking for now to avoid duplicate reports of known issues;
    hangs when emerging e.g. Firefox and seemingly anything Go
    based are nasty.
    
    One of the bugs (821403) should be OK now but tagging
    anyway for reference.
