See casadi/casadi#2611 and the attached files.

In particular the following lines from format_paramlist.c:

   int n = Len(paramlist);
   int i;

   bool print_sep = false;
   for (i=0;i<n;++i) {
   	Hash *node = Getitem(paramlist, i);

are compiled by gcc8 in the following instructions (the rest in format_paramlist_gcc8.S)

   ad1e8:	e8 23 42 f8 ff       	callq  31410 <DohLen>
   ad1ed:	31 f6                	xor    %esi,%esi
   ad1ef:	48 89 df             	mov    %rbx,%rdi
   ad1f2:	89 44 24 24          	mov    %eax,0x24(%rsp)
   ad1f6:	e8 c5 49 f8 ff       	callq  31bc0 <DohGetitem>

Which means that (Getitem) is called directly after (Len) without performing any checks and if Getitem is called with list with zero len it the assertion in the fuction will fail

how to replicate

Assembly code is generated with the following copilation commands

$ export CC="gcc-8" && export CXX="g++-8"
# $ export CC="gcc-7" && export CXX="g++-7"
$ ./autogen
$ ./configure --prefix=$HOME/.local
$ make -j4

and then disassembled with

$ objdump -d --demangle swig > swig.S

The gdb backtrace can be obtained with:

(gdb) file /home/user/.local/bin/swig
# (gdb) break DOH/list.c:167 if n>= l->nitems
(gdb) break Modules/lang.cxx:3956
(gdb) run -v -matlab -DSWIG_TYPE_TABLE=casadi -fvirtual -DWITH_DEPRECATED_FEATURES -outdir swig/matlab -c++ -I.. -I. -o swig/casadiMATLAB_wrap.cxx ../swig/casadi.i
