I experience the problem every single time I start > gdb with a multithreaded application, what information will give you this > 1000 times? If it's a race condition independent of guile, then if you get a hang even with --without-guile, then that is good data to have. I don't know if it's a race condition. It may not be. At this point I'm still collecting data. I only picked 1000 as something out of the air. Even if gdb hangs 10 times in 10 tries that's good data. Questions: What system are you on, and which version? What version of libgc are you using? What version of guile are you using? I may need to install it, as I cannot recreate this on the systems I have access to (ubuntu precise, fedora fc20). -- You are receiving this mail because: You are on the CC list for the bug.
