Bug C++ 111974 (Segmentation fault of GCC, ubuntu 23.10, compiling RefPerSys 041d5d70aefd)

2023-10-25 Thread Basile Starynkevitch 

Hello all,


Sorry for this non-minimal bug report. I was unable to make a shorter or 
minimal bug example.


RefPerSys is a GPLv3+ open source project for an inference engine. See 
http://refpersys.org/ for ambitions and some details. (I am currently 
more interested in working on RefPerSys than on debugging GCC, to which 
I did contribute earlier). RefPerSys is itself on github in 
https://github.com/RefPerSys/RefPerSys/


I am compiling RefPerSys (mostly C++ code, including some self 
generated, which is including in the below snapshot) on Ubuntu 23.10 
whose g++ has version  (Ubuntu 13.2.0-4ubuntu3) 13.2.0 on a desktop with 
AMD Ryzen Threadripper 2970WX


The RefPerSys commit is 
https://github.com/RefPerSys/RefPerSys/commit/041d5d70aefd047de4eb456432853beefffb4120 
and has a few tests: eg make test00 test01 did work a few days ago.


I uploaded to 
http://refpersys.org/refpersys-gcc13bug-snapshot-25oct2023-git041d5d70aefd0.tar.bz2 
a bzip2 compressed tarball (29246912 bytes) of md5sum 
6b1d2985ce86bd1718d05af3d93a84f9


That tarball is likely to be removed in a few months.

The disk space for the RefPerSys source code (with object files) take 
less than 200 Mbytes.


To reproduce the GCC bug, run make (GNU make 4.3 from Ubuntu) in the tarball

If you did reproduce it, please email me (Basile Starynkevitch, in 
France) to bas...@starynkevitch.net


Regards

Re: GCC 14 jit API in C++ for creating union types?

It seems that gcc_jit_context_new_union_type exists as a C callable
function in /usr/lib/gcc/x86_64-linux-gnu/14/include/libgccjit.h but
has not yet a C++ wrapping function?

Or did I misunderstood the libgccjit API?

Thanks
