gnb aborted (core dumped)

[s5uishida]

Issue Description

When build the latest main branch on Ubuntu 22.04 (Virtualbox VM) and run gnb, it aborted.

Setup Details

# cd ~/srsRAN_Project
# mkdir build
# cd build
# cmake ../ -DENABLE_EXPORT=ON -DENABLE_ZEROMQ=ON -DAUTO_DETECT_ISA=OFF
# make -j`nproc`

Expected Behavior

gnb should work without abnormal termination.

Actual Behaviour

# cd ~/srsRAN_Project/build/apps/gnb
# ./gnb
/root/srsRAN_Project/include/srsran/adt/interval.h:53: constexpr srsran::interval<T, RightClosed>::interval(U, V) [with U = int; V = unsigned int; T = unsigned int; bool RightClosed = true]: 
Assertion `start_ <= stop_' failed - Invalid interval [2, 1).
Aborted (core dumped)

Hi Shigeru,

while I am trying to reproduce it locally would you be able to rebuild it in debug and run it again?
You can do it with this cmake command:
cmake ../ -DENABLE_EXPORT=ON -DENABLE_ZEROMQ=ON -DAUTO_DETECT_ISA=OFF -DCMAKE_BUILD_TYPE=Debug

Then the gNB would produce a backtrace and you can share it here.

Regards.

Hi @AlaiaL

I created a new Virtualbox VM and tried again, and it worked fine both with and without the cmake debug option.
I do apologize for any inconvenience caused.

Hi @AlaiaL

I got the cause.

When the number of CPU cores in the VM was 1, an error occurred at starting gnb, but when the number of CPU cores in the VM was 2 or more, the error did not occur and it worked.

Previously, it worked even with 1 core, but that seems to have changed recently.

Hi @s5uishida,

Thanks for the info. I will look at it.
