<ul>

<li><I>Analysis</I>. Function start patterns found at 0x0, function signatures applied from the Data Type Manager at 0x0, and DWARF debug symbols applied at 0x0 will no longer cause stack traces. In addition, DWARF symbols with zero length address range no longer stack trace. (GT-2817, Issue #386, #1560)</li>

|

<li><I>Decompiler</I>. Fixed a bug causing the Decompiler to lose Equate references to constants passed to functions that were called indirectly. (GP-247)</li>
|
||||
<li><I>Decompiler</I>. Addressed various situations where the Decompiler unexpectedly removes active instructions as dead code after renaming or retyping a stack location. If the location was really an array element or structure field, renaming forced the Decompiler to treat the location as a distinct variable. Subsequently, the Decompiler thought that indirect references based before the location could not alias any following stack locations, which could then by considered dead. As of the 9.2 release, the Decompiler's renaming action no longer switches an annotation to <code>forcing</code> if it wasn't already. A retyping action, although it is <code>forcing</code>, won't trigger alias blocking for atomic data-types (this is configurable). (GP-248, Issue #524, #873)</li>
