the arguments str malloc is like this (it's not the same name but i pass base in argument of my rope_insert_at function)

the problem is that with my realloc on "rope->inner_string->str", the new "size" seem to be good, so no problem with that but all the characters of the argument str are changed :

like this

and i can't understand why str characters are changed during the realloc (i'm not even mentionning str in the line)

[wary coyote]

it seem than passing by a new char seem to work :

but making a copy like this will reduce the speed of my code i think

The root of this could be anything.
How about you compile with -g3 -fsanitize=address,undefined and just run the code and see what it tells you.
If that doesn't help then please share your entire code (as a codeblock, not as an image please).

[wary coyote]

for the moment i just try to "make" and get segmentation fault

[keen siren]

Well, then you could add these two compile options into your makefile

[wary coyote]

CFLAGS=-g3 -fsanitize=address,undefined?

[keen siren]

yeah

[wary coyote]

i have a lot of things

i don't really understand all but i have a lot of things like this :

undefined reference to __asan_report_load8' undefined reference to __ubsan_handle_divrem_overflow'

[keen siren]

oh, are you not on Linux?

Just share your code, that'll be easier

[wary coyote]

i'm on linux but maybe i don't have all things installed, we gave me that project like this, i don't know a lot of c

i give just the function where i have problems?

[keen siren]

The function where you have the problems + all the other functions that touched the problematic piece before (I want to be able to see how it was created, assigned a value to, etc)

[wary coyote]

okay

there s a lot

Inner_string *inner_string_new(char *str, size_t lenstr)
{
Inner_string *inner_string = (Inner_string *)malloc(sizeof(Inner_string));
if (inner_string == NULL)
{
fprintf(stderr, "Erreur d'allocation mémoire pour la structure Inner_string\n");
exit(EXIT_FAILURE);
}
inner_string->str = str;
inner_string->length = lenstr;
return inner_string;
}

i don't have problems until rope_insert_at that break my mind

[wary coyote]

i'm maybe thinking than the first time i insert it work (except maybe ajust_inner_string_length that don't seem to work that much) and the other time it may make an error

[wary coyote]

ok so the problem came from the fact than my base variable is modify when i make the realloc even if i don't mention it inside of it

[wary coyote]

this is working now, it just seem that it s too slow for the moment
