Hello,

I got several "core dumped" issues even after reinstall, for example with leafpad

Re: Core dumped issues

Do you have a coredump?

bash# echo 0 >  /proc/sys/kernel/core_uses_pid
bash# echo "core" > /proc/sys/kernel/core_pattern
bash# ulimit -c unlimited
bash# leafpad
gdb leafpad core
gdb) info threads
gdb) bt
gdb) disassemble

I have a P3 test system (no SSE2) for testing, stable and staging, there I could run leafpad..

Re: Core dumped issues

sudo echo 0 > /proc/sys/kernel/core_uses_pidand

won't cooperate as you'd thing - use

echo 0 | sudo tee /proc/sys/kernel/core_uses_pid

instead.
Also the important part is not, that it crashes, but what the gdb stuff tells you (and us) about the crash.
