Core dumped issues

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 think - 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.

Re: Core dumped issues

"Instruction non permisive" tells me "Illegal Instruction", so it's again an SSE2 or worse problem.

From the CPU-list I see "AMD Athlon(tm) XP 2000+", I'm actually astinished the machine boots at all. :-)

Sadly more and more hand-crafted optimization appears in all kind of software, we have to hunt it down
and most likely build a 486-version, which runs everywhere. I'm not there yet, but soon.. :-)

But we have to know whether it's SSE2 causing the problem (which we will try to avoid in the main build
aiming at a Pentium III as basis), or if it's something else.

See your other post: "cat /proc/cpuinfo" would be very helpfull.
