Bug#1008870: openocd: segfault when using stm32f1x config

[Matsievskiy S.V.]

Package: openocd
Version: 0.11.0-1
Severity: important
X-Debbugs-Cc: seregax...@gmail.com

Dear Maintainer,

OpenOCD segfaults when using target/stm32f1x.cfg configuration. I do not
experience this issue with newer version built from source (Open On-Chip
Debugger 0.11.0+dev-02226-gf6ffede8b).

dmesg entry:
[ 7388.531636] openocd[36055]: segfault at 14 ip 00007f64e097b12d sp
00007ffdde27a090 error 4 in libusb-1.0.so.0.3.0[7f64e0974000+f000]

Way to reproduce:
1. Connect STLinkV2
2. Run command openocd -f openocd.cfg (file is attached)

I don't have STLinkV2 hardware so am unable to reproduce. Can you
confirm the upstream git version you're using - I don't see "f6ffede8b"
in the usptream git tree.

Also, if you're able to, can you try recompiling the 0.11.0 Debian
package on your system just to narrow down that it's a fix upstream
we're looking for rather than a build issue? I *think* it's going to be
cff0e417da58adef1ceef9a63a99412c2cc87ff3 that's the issue, which means
the problem won't exist in bullseye (libusb-1.0 is at 1.0.24).

I guess the problem was with some underlying library. I had openocd
segfault on two machines (both on testing) and now everything works.
I've also openocd from 0.11.0-1 source and it works too.

The issue may be closed now.
