Bug ID: 67665
Summary: ICE when passing two empty files directly to cc1 with
-g
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: jgreenhalgh at gcc dot gnu.org
Target Milestone: ---
I typoed inputs to a script, and ended up passing the same empty file twice to
cc1, that gave me an ICE with many recent versions of trunk (at least the last
month). There is no issue when doing the same through the driver, so this
really is a bit of an edge case...
To reproduce:
touch foo.c
.../build-gcc/gcc/cc1 foo.c foo.c -g
foo.c:1:0: internal compiler error: in
dwarf2out_register_main_translation_unit, at dwarf2out.c:22590
0x79a24e dwarf2out_register_main_translation_unit
