Public bug reported: This problem occurs with crash v8.0.4 version part of Ubuntu 24.04.4 LTS, and only during live usage but not post-mortem.
The following upstream commit, part of crash-9.0.2 release describes and fixes the issue: fix eheader overflow crash-utility live session fails solid with a SEGV, where it seems that with some (new ?) Kernels and configurations /proc/kcore exposes a first “Note” program-header along with a big number of other headers (particularly when direct-map area generated from physical memory map have a lot of entries), causing eheader[] overflow (a stack underflow in fact since it is an automatic variable!) because the whole size exceeds MAX_KCORE_ELF_HEADER_SIZE. This problem still occur with latest utility version, and the following patch has been proven to fix.
