If you ever report any of these bugs, they might get fixed.

Rumors of bugs, and slanderous comments, are not bug reports!  It's hard to
fix a rumor of a bug.

PS:  It sounds to me like you are debugging optimized code.  Read The
Forking Manual about debugging optimized code.  Here, to save you the
trouble, I'll quote from the GCC manual:

     Unlike most other C compilers, GNU CC allows you to use `-g' with
     `-O'.  The shortcuts taken by optimized code may occasionally
     produce surprising results: some variables you declared may not
     exist at all; flow of control may briefly move where you did not
     expect it; some statements may not be executed because they
     compute constant results or their values were already at hand;
     some statements may execute in different places because they were
     moved out of loops.
