Greetings!
In dmesg I see stuff like:
rpmbuild[3842] trap int3 rip:402d9e rsp:7fbfffb540 error:0
rpmbuild[3842] trap int3 rip:4026d1 rsp:7fbfffb538 error:0
sh[3843] trap int3 rip:415f39 rsp:7fbffff8c8 error:0
sh[3843]: segfault at 0000000000000000 rip 0000000000000000 rsp 0000007fbffff8b8 error 14
rpmbuild[3842] trap int3 rip:402dea rsp:7fbfffb540 error:0
rpmbuild[3842] trap int3 rip:4025d1 rsp:7fbfffb538 error:0
rpmbuild[3842] trap int3 rip:402ced rsp:7fbfffb540 error:0
rpmbuild[3842] trap int3 rip:4027c1 rsp:7fbffff688 error:0
segfault is scarry.
Are these traps harmless or do they mean some serious software/hardware problem?

They just chose to show a small message in the log when some program
behaves badly. Nothing to worry about, more than your programs
misbehaving.
