Carr <jfc@mit.edu> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jfc@mit.edu --- Comment #3 from John F. Carr <jfc@mit.edu> --- I can confirm this running native stable/13 on Ampere eMAG and current on Cortex A-57. The program sometimes hangs. Running in a debugger I get occasional addressing errors (segfault or bad address). I think the errors are caused by a bad interaction between lldb and system calls. Conceivably it is a scheduling problem that only shows up with a debugger. -- You are receiving this mail because: You are the assignee for the bug.help
