Bug ID: 25917
Summary: segmentation fault with -gdwarf-5
Product: binutils
Version: 2.35 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: ndesaulniers at google dot com
CC: nickc at redhat dot com
Target Milestone: ---
With the fix from https://sourceware.org/bugzilla/show_bug.cgi?id=25612, I can
now compile a Linux kernel with Clang and assemble with GNU as with DWARF5.
Testing the same patch set with GCC 7.5+ GNU as (ToT) produces a crash in GNU
as. I reran the kernel build with `make V=1` to get the compiler invocation,
then reran that with `-v` to get the assembler invocation. From there, I've
trimmed it down to the following invocation and input.
$ PATH=~/binutils-gdb/binutils:$PATH as -gdwarf-5 -o scripts/mod/empty.o
/tmp/ccDA463U.s
/tmp/ccDA463U.s: Assembler messages:
/tmp/ccDA463U.s: Internal error (Segmentation fault).
Please report this bug.
