Hi,
this is my first mail to this list so sorry if I do something wrong.
I posted a bug report on sparkfun openocd forum but did not get a lot of
answers there...
https://forum.sparkfun.com/viewtopic.php?f=18&t=36484&e=0
I think it is a clear memory corruption problem in openocd.
I find reallocate calls only in the parser of the SVF file
so probably it is a feature of my svf file that was not foreseen.
I can help debugging but I need some help and advise. There is a little
bit of too many new things at the same time (debugginig on a raspberry,
openocd itself, I have zero knowledge of svf language)
What I do on the raspberry is:
sudo openocd -f interface/sysfsgpio-raspberrypi.cfg
then from another terminal on the raspberry:
telnet localhost 4444
scan_chain
svf <the svf file>
I don't know how to declare my target (igloo fpga) but it seems to me
that an atomatic tap is found by scan_chain.
I attach here the start of the svf file that create the crash (my mailer
is rewrapping the lines, in fact this can be a problem for this bug):

In fact mailer rewrapped those lines.
