Check that they're all running the same kernel version, check for kernel updates. This does not sound like a GDB problem.
They are running the same kernel !
Effectively, I don't think it's a gdb problem because the error occurs for the others debuggers.
I have checked the list and the versions of packages installed, the configuration, all seems identical.
What can make the debuggers fail while setting breakpoints ?
I tried to build new gdb on this system but it fails during configure. It fails in the conftest cheking division by zero.
I built the conftest and run gdb on it. The error occurs when catching SIGFPE signal, gdb is blocked waiting!
