Giac consistent segfault in giac::zmakelinesplit on macos M2

[vbraun]

Steps To Reproduce

Build Sage on macos M2

Expected Behavior

Testsuite should succeed

Actual Behavior

There are a few giac-related segfaults, for example this one in void giac::zmakelinesplit<giac::tdeg_t14>(giac::zpolymod<giac::tdeg_t14> const&, giac::tdeg_t14 const*, std::__1::vector<giac::tdeg_t14, std::__1::allocator<giac::tdeg_t14> > const&, void*, std::__1::vector<int, std::__1::allocator<int> > const&, std::__1::vector<unsigned short, std::__1::allocator<unsigned short> >&, std::__1::vector<unsigned short, std::__1::allocator<unsigned short> >*, int):

I need to reproduce that with giac natively. I understand it's a call to gbasis with katsura 9 (but maybe with katsura10, katsura indexation is not always consistent)

Can you reproduce the crash while running from giac interpreter, that is if you put the code above in a text file, say katsura9 and run
icas katsura9
N.B.: If you have the source code of giac, this file is already available in the examples/groebner subdirectory.
If you can reproduce the crash, I will also need some additional informations: how many threads are processed in parallel? (this is displayed at startup with something like
// Maximum number of parallel threads 1
)
And I'll check when I'll go back at the office where I have a mac.
Thank you

Thanks for the detailled information. The lldb session would be more interesting if giac was compiled with debug infos, it should be possible to see the precise line where the segfault happens, and examine variables. I'll do that when I'll have access to a Mac, should be on Tuesday November 5th or Wednesday 6th.
Hopefully, that's a mono-thread execution, this should be easier to fix than a multi-threaded gbasis.

It seems your source code is not synchronized with mine, so it's hard to find some useful information here, most probably the x variable refers to a non existent address, and the y variable itself is suspect (dimension 0). Moreover since there are optimizations in the data structure, printing variables is not very informative for the type of x and y. I have a gdb macro in my .gdbinit file

echo Defining v as print command for giac types\n
set print repeats 0
define v
print ($arg0).dbgprint()
end

if it applies to lldb as well, then you can type v varname instead of p varname. Otherwise p varname.dbgprint() will display a monomial power in a more informative way.
But it's probably best to wait next week, I'll check with my own compilation of giac on macos and debug it myself if it fails for me too. BTW, my binary distribution of Giac/Xcas for MacOS is available here if you want to check before :

and could not reproduce a segfault, size(H) returns 143.

My guess is that there is probably a configuration issue. My config.h was generated by ./configure with CXXFLAGS defined in the shell script mkosx from giac-1.9.0 directory, using libraries from brew installed in opt for arm64 architecture:
(export CXXFLAGS='-std=c++11 -I/opt/homebrew/include -I/opt/homebrew/Cellar/fltk/1.3.9/include -I/opt/homebrew/opt/readline/include -I/opt/homebrew/opt/jpeg/include -I/Applications/usr/include/ -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT -fPIC -g -O2').
