Bug ID: 31595 Summary: Abort in AArch64 disassembler's get_sreg_qualifier_from_value() function Product: binutils Version: unspecified Status: NEW Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: nickc at redhat dot com Target Milestone: --- Attempting to disassemble the latest version of glibc compiled for the AArch64 for Fedora Rawhide results in: $ objdump -D lib64/libc.so.6 objdump: opcodes/aarch64-dis.c:251: get_sreg_qualifier_from_value: Assertion `value <= 0x4 && aarch64_get_qualifier_standard_value (qualifier) == value' failed. Abort (core dumped) This was using the version of libc.so.6 obtained from glibc-2.39.9000-10.fc41.aarch64.rpm but I can also reproduce the problem with a libc.so.6 from RHEL-9. I suspect that any recent-ish version of libc.so will do. I suspect that the issue is with the processing of the rcpc3 size field, since the stack backtrace shows that get_sreg_qualifier_from_value is called from do_special_decoding at opcodes/aarch64-dis.c:2678. -- You are receiving this mail because: You are on the CC list for the bug.
