Now I don't understand why malloc isn't working

typedef union
{
int64_t int_d;
double number_d;
} Token_data;

typedef struct
{
Token_type type;
Token_data data;
} Token_t;

Token_t *my_token = (Token*) malloc(sizeof(Token_t))

@matrix in which way is it not working?

@Binkle Crashes with SIGABRT

@matrix is the "(Token*)" cast a typo on the post or is that direct from your code? I would expect that to not compile though so I doubt that's the issue

@Binkle That's a typo

@matrix does it crash on malloc or does it crash on access?

@Binkle On malloc

@matrix if you print "sizeof(Token_t)", what does it think that is?

@Binkle malloc.c:2379: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.

@matrix @Binkle I thinnk he’s looking for

printf("%d\n", sizeof(Token_t));

Which is a better question than mine tbh

@ademan @Binkle No, that's the error when I try to print it

@matrix @ademan is that after taking out the malloc statement and replacing it with the print statement? Or are you including both? If the latter, take out the malloc statement.

@Binkle @ademan Wtf, now that I commented out a previous few lines, the print works and says 24.
Fuck. I think a previous function might be doing something weird. Malloc seems to work

@matrix @Binkle oh, can we get the whole program verbatim? sounds like you’re clobbering your memory (welcome to C)
