Bug ID: 60339
Summary: gnat weird DW_AT_abstract_origin
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: jan.kratochvil at redhat dot com
Host: x86_64-unknown-linux-gnu
Description of problem:
FSF GDB HEAD internal errors on reading gcc/gnatbind using -readnow.
GDB will be changed to just make a 'complaint' as GDB must not crash on invalid
DWARF file. But still the gnat-produced DWARF seems incorrect to me.
Version-Release number of selected component (if applicable):
GNU gdb (GDB) 7.7.50.20140224-cvs (gdb-7.7 is too old)
FAIL: r208119
Steps to Reproduce:
../gcc48/configure --enable-languages=ada --enable-bootstrap
make profiledbootstrap
../fresh-new-gdb/gdb/gdb -readnow gcc/gnatbind
Actual results:
Reading symbols from gcc/gnatbind...expanding to full
symbols...dwarf2read.c:8032: internal-error: process_die: Assertion
`!die->in_process' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

readelf -wi gcc/gnatbind
concrete instance tree (Out-of-Line Instance):
<1><47562>: Abbrev Number: 62 (DW_TAG_subprogram)
<47563> DW_AT_abstract_origin: <0x46678>
<47567> DW_AT_low_pc : 0x4517e0
<4756f> DW_AT_high_pc : 0x261
abstract instance tree:
<1><46678>: Abbrev Number: 48 (DW_TAG_subprogram)
<46679> DW_AT_name : atree__copy_separate_tree
<46684> DW_AT_inline : 1 (inlined)
<2><46689>: Abbrev Number: 112 (DW_TAG_subprogram)
<4668a> DW_AT_name : atree__copy_separate_tree__copy_entity
<46695> DW_AT_low_pc : 0x450ca0
<4669d> DW_AT_high_pc : 0x3c9
- why are specific PCs in _abstract_ instance tree?
- BTW the tree has 301 DIEs, that seems too large for an abstract instance
tree
BTW master (4.9 - r208124) failed on GNAT internal error during bootstrap.
