</code></pre><p style="margin: 0px 0px 1em; padding: 0px; border: 0px currentColor; clear: both; font-size: 15px;">Then I got a failure of "SBProcess is invalid" when printing a wstring variable.</p><p style="margin: 0px 0px 1em; padding: 0px; border: 0px currentColor; clear: both; font-size: 15px;">My type summary function has the following, which I believe is where the error is encountered:</p><pre style='margin: 0px 0px 1em; padding: 5px; border: 0px currentColor; width: auto; overflow: auto; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; -ms-word-wrap: normal; max-height: 600px; background-color: rgb(239, 240, 241);'><code style='margin: 0px; padding: 0px; border: 0px currentColor; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; font-size: 13px; white-space: inherit; background-color: rgb(239, 240, 241);'>content = lldb.process.ReadMemory(bufferAddr, byteCount, error)
</code></pre><p style="margin: 0px 0px 1em; padding: 0px; border: 0px currentColor; clear: both; font-size: 15px;">Maybe this is because "process" is not assigned yet when the type summary is added during auto-loading? Or this is a bug in lldb? Does anyone know how to work around this issue?</p><p style="margin: 0px 0px 1em; padding: 0px; border: 0px currentColor; clear: both; font-size: 15px;"> </p><p style="margin: 0px 0px 1em; padding: 0px; border: 0px currentColor; clear: both; font-size: 15px;">Thanks much</p></div></div> <BR><table style='margin: 0px; padding: 0px; border: 0px currentColor; text-align: left; color: rgb(36, 39, 41); text-transform: none; line-height: 16.9px; text-indent: 0px; letter-spacing: normal; font-family: Arial, "Helvetica Neue", Helvetica, sans-serif; font-size: 13px; font-style: normal; font-weight: normal; word-spacing: 0px; white-space: normal; border-collapse: collapse; border-spacing: 0px; orphans: 2; widows: 2; background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px;'><tbody style="margin: 0px; padding: 0px; border: 0px currentColor; font-size: 13px;"><tr style="margin: 0px; padding: 0px; border: 0px currentColor; font-size: 13px;"><td class="votecell" style="margin: 0px; padding: 0px 15px 0px 0px; border: 0px currentColor; font-size: 13px; vertical-align: top;"><div class="vote" style="margin: 0px; padding: 0px; border: 0px currentColor; text-align: center; font-size: 13px; min-width: 46px;"><div class="favoritecount" style="margin: 0px; padding: 0px; border: 0px currentColor; text-align: center; font-size: 13px;"> </div></div></td><td class="postcell" style="margin: 0px; padding: 0px; border: 0px currentColor; font-size: 13px; vertical-align: top;"><div style="margin: 0px; padding: 0px; border: 0px currentColor; font-size: 13px;"> </div></td></tr></tbody></table> </div></body>
