Top Forums Programming how to avoid the segfault from Address 0x1cd00000103 out of bounds Post 302276986 by otheus on Thursday 15th of January 2009 04:48:52 AM

"out of bounds" means "invalid memory address". You avoid it by properly mallocing memory before using it.

I hate to say this, but you seem very confused about pointers. I think you need to read a very concise summary on C pointers.

In the code you provide, you are trying to assign values to the address...
Code:
node->des = 0;

You should instead be doing:
Code:
*(node->des) = 0;

And your loop should be:
Code:
while ( *(  tr->root->is_done ) ) {
... 
}

Also, root itself is a pointer. So you first need to allocate it:
Code:
tr->root = malloc(sizeof(struct node_t));
tr->root->hood = malloc(sizeof(double*));

"tr" is also a pointer, and this needs to be allocated too, but I have no idea what kind of structure it is.


Also, this structure is very unusual. I cannot imagine why you want every element to be a pointer to something!

NAME
UilDumpSymbolTable -- Dumps the contents of a named UIL symbol table to standard output SYNOPSIS
#include <uil/UilDef.h> void UilDumpSymbolTable( sym_entry_type *root_ptr); DESCRIPTION
The UilDumpSymbolTable function dumps the contents of a UIL symbol table pointer to standard output. root_ptr Specifies a pointer to the the symbol table root entry. This value can be taken from the parse_tree_root part of the Uil_com- pile_desc_type data structure returned by Uil. By following the link from the root entry, you can traverse the entire parse tree. Symbol table entries are in the following format: hex.address symbol.type symbol.data prev.source.position source.position modification.record where: hex.address Specifies the hexadecimal address of this entry in the symbol table. symbol.type Specifies the type of this symbol table entry. Some possible types are root, module, value, procedure, and widget. symbol.data Specifies data for the symbol table entry. The data varies with the type of the entry. Often it contains pointers to other symbol table entries, or the actual data for the data type. prev.source.position Specifies the end point in the source code for the previous source item. source.position Specifies the range of positions in the source code for this symbol. The exact data structures for each symbol type are defined in the include file UilSymDef.h. Note that this file is automatically included when an application includes the file UilDef.h. RELATED
