I think I've at least isolated the code change that leads to this mysterious exit, just don't understand the details yet. I am dealing with a huge amount of code in C++ with tons of cpp files.
There is NO WARRANTY, to the extent permitted by law. For historical reasons our product uses the evil linker flag -Bsymbolic. Having a problem logging in?
Registration is quick, responsible and absolutely free. If I try to set a breakpoint, such as by break test. Update for exit message change. Missing separate debuginfos, use: debuginfo-install glibc. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to tout with system and network administration. After I applied them again in sequence, I can no longer repro the problem, even with things restored to the original state.

Re: RFC: change message - I was checking a program I'm working on with valgrind for memory leaks and apparently it found an invalid memory access and threw a segfault. Does it show the correct path in Starting program: after you run?
Anybody know of some other mysterious trigger for exit that can't be caught? EDIT: the problem is now academic only. I tried binary search debugging, backing out a subset of my changes the problem went away. After I applied them again in sequence, I can no longer repro the problem, even with things restored to the original state. EDIT2: I found one reason for this sort of error recently, which may have been the original source for this problem. For historical reasons our product uses the evil linker flag -Bsymbolic. Among the side effects of this is that when a symbol is undefined but called, the GLIBC runtime linker will bomb in exactly this way, and you see it in the debugger as a process exited with 0177. That would be consistent with the fact that I was unable to catch this with an the exit breakpoints in the debugger. Edit: Also worth noting that you can use mnemonic names, rather than syscall numbers. Breakpoint 3 at 0x2aeea040f250 0x00002aeea040f250 : mov %fs:0x0,%r9... I think I've at least isolated the code change that leads to this mysterious exit, just don't understand the details yet. You might also try linking statically, just to take a stack of potential gdb complications off the table. But I'm right about wait status. I'm obviously not talking about the signal number, but the status wait 2 returns for a stopped process. But I agree that's not what is happening here. Now exit appeared when I've invoked some scenario that used function that was undefined.
