Thread: Valgrind - Invalid read of size 1

I'm getting the next error when running memcheck with valgrind:

Invalid read of size 1

==2511== at 0x4C29852: __GI_strcpy (mc_replace_strmem.c:313)
==2511== by 0x401A76: getstring (reader.c:125)
==2511== by 0x400A0E: main (reader.c:22)
==2511== Address 0x7fefffcfb is just below the stack ptr. To suppress, use: --workaround-gcc296-bugs=yes

Code:

 void getstring{
char test[1024];
...
string = readstring(filepointer);
strcpy(test,string);
...
}

I already searched on stackoverflow, etc. And i guess it has something to do with strcpy(). Help on how to solve this error woud be appreciated.

Post the complete function and the definition of readstring().

It's an invalid READ, so it's not to do with writing to the stack buffer. Such stack errors are impossible for valgrind to check, anyway. What's more likely is that readstring() is not null-terminating the string correctly, causing strcpy() to read past the end.
