--- Comment #4 from Henning Meyer <hmeyer.eu at gmail dot com> ---
I was able to reproduce the SIGBUS with the provided input on elfutils 0.192.
The SIGBUS is a red herring.
Section 5 in the provided input has an alignment of 0x10000000000.
This causes this line in elf32_updatenull.c function updatenull_wrlock
(line 371 in my checkout)
size = (size + sh_align - 1) & ~(sh_align - 1);
to return a size of 0x10000000000 plus change.
Everything else is a consequence of mmaping and writing a file of that size
