Description d.binderman 2004-03-02 21:33:12 UTC 
Description of problem:

I just tried to compile Core2 Test1 package prelink-0.3.0-20

The compiler said

prelink.c(348): remark #592: variable "data" is used before its value
is set

The source code is

         free (data.d_buf);

Calling free on uninit local variable data is deeply unwise.  Suggest init
data.d_buf before first use.

Thanks, fixed in my tree.  Bigger bug is that GCC doesn't warn about
this (only when the variable is not aggregate).  ++todo.
