[Solved] A bug or build issue in declaring TF1Convolution and TF1?

ROOT Version: 6.24/00 and also 6.25/01
Platform: linuxx8664gcc
Compiler: 11.3.1 20220421 (Red Hat 11.3.1-2)


I’m simply trying the following:

TF1Convolution *f_conv = new TF1Convolution("gaus", "expo", 750, 1000, true);

TF1 *f = new TF1("f", *f_conv, 750, 1000, f_conv->GetNpar());

But, ROOT crashes without any warnings/errors and throws me back to the linux command prompt!

I have built both the versions of the ROOT, for example, with:

cmake -DCMAKE_INSTALL_PREFIX="../root/pro" -Dall="on" /opt/root/root-6.24.00

followed by

cmake --build . -- -j6

on my laptop with 32GB RAM and 8 processors.

Can you please tell whether I’m doing anything wrong?

I confirm that the above issue vanishes after installing the latest ROOT release, i.e., 6.26/06.
