Debian Testing build => free() invalid pointer

[YannChemin]

Describe the bug compiling from git clone now, on a updated Debian testing today. When running the xmrig, it says "free(): invalid pointer Aborted"

To Reproduce

1. sudo apt-get install git build-essential cmake libuv1-dev libssl-dev libhwloc-dev
2. git clone https://github.com/xmrig/xmrig.git
3. mkdir xmrig/build && cd xmrig/build
4. cmake ..
5. make -j$(nproc)
6. ./xmrig -c theconf4xmrig.json

Expected behavior xmrig to launch The binary version (latest download) works perfectly on the computer.

Required data

• terminal says:

free(): invalid pointer Aborted

• Config file or command line (without wallets)
• OS: Debian Testing updated today

Additional context

It might be something wrong with your dependencies. Try to build using advanced build instructions, it will create the same binary as in official releases.

[YannChemin]

I removed the previously used xmrig git directory and used these steps:

1. sudo apt-get install git build-essential cmake automake libtool autoconf
2. git clone https://github.com/xmrig/xmrig.git
3. mkdir xmrig/build && cd xmrig/scripts
4. ./build_deps.sh && cd ../build
5. cmake .. -DXMRIG_DEPS=scripts/deps
6. make -j$(nproc)

The result is the same:

free(): invalid pointer
Aborted

[SChernykh]

Is it the full output in the terminal? Nothing else? Also, can you run it under gdb and get a call stack? Run gdb --args ./xmrig then in console type run and when it crashes type bt

[YannChemin]

After changing opencl to false in .xmrig.conf, then it worked

[SChernykh]

#18 0x00007ffff7f9cbc6 in clGetPlatformIDs () from /opt/rocm-6.0.1/lib/libOpenCL.so
#19 0x00005555557e8ea8 in xmrig::OclLib::getPlatformIDs() ()

XMRig just calls clGetPlatformIDs here, and then it crashes deep inside libamdocl64.so which is not a part of XMRig. Maybe (maybe) your OpenCL headers are incompatible with .so libraries you have there, which is why you have issues when compiling XMRig locally.
