avrdude crashes after every run

[danboid]

I have installed avrdude under Haiku b5 amd64. I have tried using my USB AVR ISPMKII programmer to program my Uzebox and it does work but it crashes at the end of every run.

I have attached a core dump from avrdude after one of these crashes.

[danboid]

The core dump was 12 MB when compressed with xz -9 so I'd need to split it to share it on here.

Just attach the report, please. But odds are this a bug in the avrdude port and not Haiku itself.

or a bug in libusb.

[danboid]

Yes was unsure about where to post this tbh but I thought better post it somewhere than not raise it at all. Sorry if this is a packaging bug or whatever which I suppose is just as likely.

I have split that beautiful coredump for you.

This crash not only happens after every run of avrdude, I've also seen it on two different machines, a laptop and a desktop both running b5.

[danboid]

You should be able to uncompress those split files using the command:

cat Haiku-avrdude-usb-core.tar* | tar xvf -

danboid, I think waddlesplash asked to just attach the crash report.

[waddlesplash]

Indeed, I don't want the core file.

avrdude crash report

Could be a bug either in libusb or the USB Kit, not immediately clear from the report.

[danboid]

I dunno if it helps you at all but the avrdude command I'm using is:

avrdude -c avrispmkII -P usb -p m644 -U flash:w:Bootloader5.hex

See ​https://uzebox.org/wiki/Avrdude

Haiku is almost the optimal platform for Uzebox devs. I think it would be if we could fix this.

It is arguably easier to build the Uzebox repo under Haiku than Linux because I can install Haiku faster than most if not all Linux distros, Windows and so much faster than macOS its not worth mentioning.

Can you please try with the guarded heap?

LD_PRELOAD=libroot_debug.so MALLOC_DEBUG=g program...

[danboid]

Prefixing avrdude with

LD_PRELOAD=libroot_debug.so MALLOC_DEBUG=g

Didn't stop it from crashing after running.

[waddlesplash]

I meant to generate a new debug report and attach it here with the guarded heap; it should crash in a different place and/or with a different message.

[danboid]

New debug report attached. Please excuse the incorrect date.

[waddlesplash]

There does appear to be at least one issue with the USB Kit here at least.

I have not seen crashes in a while, but I think I don't own an avrispmk2 compatible device. So maybe I didn't test this specific combination and avrdude is working fine with other programmer types (I use mainly an stk500 development board, and lufa bootloader these days)

[waddlesplash]

PulkoMandy: can you try with the guarded heap with one of the devices you do have and see if a similar crash occurs anyway?

[pulkomandy]

The stk500 is accessed through a serial port and doesn't use libusb. I'll see if I can find and test one of my devices using a bootloader
