Bug ID: 26549
Summary: GDB crashes when performing `backtrace` on a binary
with full symbols enabled
Product: gdb
Version: 9.2
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: backtrace
Assignee: unassigned at sourceware dot org
Reporter: faraz.abrar9 at gmail dot com
Target Milestone: ---
Hello,
This issue is very recent. I have built GDB 9.2 (downloaded from
https://ftp.gnu.org/gnu/gdb/gdb-9.2.tar.xz) and tried to run V8 built with full
debugging symbols. After running the interpreter, attempting to CTRL+C and
`backtrace` will cause the following error:
```
../../gdb/dwarf2read.c:5264: internal-error: compunit_symtab*
dw2_find_pc_sect_compunit_symtab(objfile*, bound_minimal_symbol, CORE_ADDR,
obj_section*, int): Assertion `result != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
This is a bug, please report it. For instructions, see:
<http://www.gnu.org/software/gdb/bugs/>.
Aborted (core dumped)
```
The binary I was using can be found here (it is nearly 400MB):

If you need more information, let me know :)

I checked and confirmed that the issue is with the gdb `index` section that is
added at build time. V8 actually comes with a tool that lets you remove the
index. You can run it by doing the following from the V8 root directory:
`build/gdb-add-index -r out/x64.release/d8`
Replace the last parameter with the path to the `d8` binary, and it'll remove
the index section. This does indeed solve the issue.

Could you possibly try gdb from git?
I don't know whether it will work or not, but it would
be nice to find out.

Hello,
I'm encountering the same issue with gdb 10.2, but I'm not using --gdb-index

I think it's probably a separate issue then.
However - can you try a newer gdb?
I feel like there were some bug fixes in this area.
