I have just learned that under Linux there's the environment variable MALLOC_CHECK_
With MALLOC_CHECK_=3 we will see data about all malloc() and free() calls.
I will try this on my machine tomorrow, but since the error doesn't happen on my system I will probably not see anything useful.

Good news: It seems to work with Ubuntu 20.04 LTS. Don't ask me why.

This error doesn't happen on my system, but I will see what I can do.
Also, I still don't know where this comes from:

I just compiled from latest release.
Tried with many intensities and OC settings,
Intensity more than 17 start the error as soon as miner starts
Lower intensities gives error with delay

Probably I have a similar issue #254
I try neoscrypt with -i 18

Is this also happening if you try this?
ccminer -a lyra2v2 --benchmark
or this
ccminer -a neoscrypt --benchmark

I have just tried mining lyra2v2 with -i 20 for about 10 minutes, but there's no error (Ubuntu 16.04)

@KlausT benchmarking seems working fine, with neoscrypt at least.
However, the problem with real mining, no matter what intensity I use

commented on August 17, 2024
For me it looks like a bit of mess doing some pointer math... As I understand, list_entry def is used only once in the whole codebase, exactly in tq_pop function. Maybe you could just inline it there, with explicit clear math and everything?
from ccminer.
KlausT
commented on August 17, 2024
Yeah. Actually, the whole tq_pop / tq_push thing is a mess.
Well, it's historic code that hasn't been changed for a while.

That's really wierd.
The same binary is running just fine on my system (Ubuntu 16.04 LTS)
I'm out of ideas

By the way, I have an Intel i5 4570 with 16GB RAM.
I don't know if this is relevant.

I tested on i3 with 8gb ram, don't think that's relevant.
Leave it be...
Let's hope not more people get into this problem, for now it looks like there is only 2.

This error free(): invalid pointer appears when cuda of your system is older than the version of ccminer.
Faced with the same error today i have cuda 9.1 and with ccminer 8.22 which is for cuda 9.2 gave me this error,
downgrade to ccminer 8.20 which is for cuda 9.1 working perfect.

Short summary of what I found out:
With most Linux distros ccminer is crashing when it finds the first share.
In the workio_thread there's a free call with an invalid address.
With Windows everything works fine.
There's an incompatibility somewhere, but I can't find it.
Maybe I could try Ubuntu 20.04 to see if anything has changed.
