OS/arch/bits (mandatory)	Debian 12 x86/64
File format of the file you reverse (mandatory)	ELF

Expected behavior

Fast.

Actual behavior

Slow & dies because of OOM.
Running with

rizin -e bin.strings=false vmlinux

results in OOM most probably. Other times it's just 10+ mins before startup.

If you run it with

rizin -e bin.strings=false -e bin.dbginfo=false vmlinux

it starts ok in about 3-5 seconds.

Steps to reproduce the behavior

• Compile linux kernel with debug symbols
• Run rizin as above

@pelijah noted the process may be killed too early. Re-ran callgrind on a better hardware. See above.
