The purpose of the tool is to access/configure a PCI-express cards that has some firmware running on it. I made

some slight change to code,nothing significant and suddenly got a "Bus error". I know that is is caused by unaligned memory access, but in the above context is it more likely to be in the firmware memory, i.e a firmware read across the PCI-express bus. I certainly don't believe that my small software change could have caused the "Bus error". Another surprising fact is that a different version of software is working well with this firmware. Can anyone throw some light on the issue. linux debugging bus share|improve this question edited May 3 '11 at 13:44 skaffman 276k62614652 asked May 3 '11 at 13:40 liv2hak 3,8391659106 closed as off-topic by Ciro Santilli 烏坎事件2016六四事件 法轮功, Yu Hao, Chris Loonam, John Pirie, Rob Aug 7 '15 at 16:35 This question appears to be off-topic.

When I typed "exit", in normal user, a message appeared: The child process exited normally with status 135. It never appeared before. How can I fix that? I need the terminal to install things because the package installer application process sleeps for some bus error linux reason. I don't know if it's related, but this problem started to happen to all users after this incident. gnome-terminal share|improve this question edited Jun 18 at 13:05 Jeff Schaller 10.5k51939 asked Dec 31 '15 at 0:44 Patrick 1135 Look at /var/log/syslog and /var/log/dmesg. Also, look at /var/log/apt/*. –RobertL Dec 31 '15 at 1:00 @RobertL dmesg is empty, and the apt/* ones doesn't show anything past the usermod incident. I couldn't open the syslog, it just froze the whole thing. –Patrick Dec 31 '15 at 1:27 In the other question you said it was a fresh install. Is it too late to re-install? –RobertL Dec 31 '15 at 2:10 1 Seems like faulty RAM, try to run memtest, either from command line, or from a LInux DVD that has it (from the top of memory, knoppix has it, I know there are others, including some known distros) –Rui F Ribeiro Dec 31 '15 at 8:09 @RobertL, nope, I ended doing that. –Patrick Dec 31 '15 at 13:58 | show 2 more comments active oldest votes Know someone who can answer?

What would cause a bus error? I searched google for a cause, but came up with some conflicting reports... Could it be caused by [lack of] disk space? A lot of the pages I found mentioned linking with the incorrect versions of the library. But in that case, would it compile correctly? Basically, I am curious as to why we had a job dump core on a bus error. It ran nearly to normal completion time, then simply poo-pood. In the case that it may make a difference, it's a job that interfaces with an Oracle database on HP-UX 11. The things that had changed were that the process was recompiled, AND we were at 96% (df -k) on that disk... Not too important for me to know right now, but I am curious, and who wants to wait for developers to tell me what happened?

This is almost always the result of dereferencing a pointer that contains an illegal value. Here is a program that, I think, will compile with every C or C++ compiler, but should cause a bus error when the second printf is attempted...
