Bug ID: 24426
Summary: Binutils 2.28.1 segfault when presented (any) linker
script on riscv64
Product: binutils
Version: 2.28
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: kallisti5 at unixzen dot com
Target Milestone: ---
Providing --script= of any kind results in a segfault from ld on riscv64.
An empty linker script will result in the same segfault.
Removing --script= results in a linker working as expected.
Here's a valgrind output to show some more backtrace information:
