<div class="markdown_content"><p>tds2pdb has a wrong segMap structure definition:<br/> struct CVssSegMapSegDesc {<br/> ...<br/> WORD offset; /*<em> Offset of logical segment within physical segment. !!<br/> Always 0. </em>/ !!<br/> WORD cbSeg; ///&lt; Size of segment.<br/> These fields are defined as unsigned long (4 bytes) in Microsofts headers:<br/> typedef struct OMFSegMapDesc<br/> ....<br/> unsigned long offset;<br/> unsigned long cbSeg;<br/> } OMFSegMapDesc;</p> <p>Another error is probably the result that the uploaded tds2pdb.exe was compiled with 2-byte structure field alignment, that leads to wrong written name prefix in PROCSYM32:<br/> typedef struct PROCSYM32 {<br/> ...<br/> +36 CV_PROCFLAGS flags; - this field is 1 byte in size, but tds2dbg writes a 2-byte field<br/> +37 unsigned char name<span>[1]</span>; // Length-prefixed name<br/> } PROCSYM32;<br/> Thus name length is always zero and symbols are seen without names.</p></div>
