Running test 260 sometimes but not always crashes.
The problematic code seems to be in scan.c (merger_add) :
Although the comment says, that OUT need not be initialised,
this code:
case 3:
if (in->type == T_STRING)
{
out->string = concat (out->string, in->string);
return -1;
}
can segfault if out->string.string == 0 and out->string.length > 0
This can happen because in lexer.c (lex_source_get_lookahead) passes
the address of a variable declared on the stack:
struct token out;
int retval = merger_add (&m, &lex_stage_nth (&src->merge, i)->token,
&out);
