heap_trace_dump dont print function name

[Xmow49]

Hi,

On I have a memory leak on my esp32c6 using esp idf;
I followed https://docs.espressif.com/projects/esp ... debug.html to debug.

I successfully run the code; and get this:

Code: Select all

================================

But now I'm not very helpful; I don't have functions name...
I use ESP IDF monitor and I tried a lot of settings:
- disable compile optimisation
- use a debugger to read the address: but it doesn't find any function.

Could someone help me pls?

Many Thanks

I am facing the same issue. I tried both standalone and host based options, I never get the caller address. I am also using esp32c6, I start thinking that this could be the issues. I tried on windows, wsl, virtualbox and on a separate linux system, I get the same result. This is sad

I found the issue after tens of hours of debugging. It is mentioned in the esp config files that "HEAP_TRACING_STACK_DEPTH" is "Disabled for RISC-V due to `__builtin_return_address` " therefore the depth is 0 and therefore it does not store this info. very sad
