PoC for an assertion failure
Hi,
An assertion failure was discovered in the latest commit 1a9fe4b of elfutils
0.179, as demonstrated by eu-objdump via a crafted file.
To reproduce: eu-objdump -d PoC
Valgrind says:
objdump: ../../libcpu/i386_disasm.c:449: x86_64_disasm: Assertion
`correct_prefix == 0 || (prefixes & correct_prefix) != 0' failed.
