Bug ID: 22127
Summary: as segfaults assembling invalid .reloc
Product: binutils
Version: 2.30 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: james410 at cowgill dot org.uk
Target Milestone: ---
I just noticed that a source file containing an invalid .reloc involving local
symbols causes as to segfault. This affects at least x86_64 and mips (but
probably everything). This example was done for mips:
$ cat test.s
.reloc .La,R_MIPS_32,.Lb
$ gdb --args ../build-mips/gas/as-new test.s
[...]
Reading symbols from ../build-mips/gas/as-new...done.
(gdb) r
Starting program: /srv/jcowgill-priv/workspace/binutils/build-mips/gas/as-new
test.s
test.s: Assembler messages:
test.s:2: Error: invalid offset expression
Program received signal SIGSEGV, Segmentation fault.
