Debugger broken in FPC3.2.0 textmode IDE ?
lazarus / 65-FV-Textmode IDE

Is anyone still using the textmode IDE under windows 10 and has issues
with the integrated debugger ? The disassembler only produces
ridiculous snippets, see this here for a complete matrix solver...

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i Dump of
assembler code for function SOLVE:334     end;$004146A7:      pop  
 %ebx$004146A8:      mov    %ebp,%esp$004146AA:      pop  
 %ebp$004146AB:      ret$004146AC:      add    %al,(%eax)$004146AE:  
  add    %al,(%eax) End of assembler dump. 
I thought disabling optimisations might help, and recompiled using the
most conservative and debugger friendly settings, and the output is :-

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i Dump of
assembler code for function SOLVE:End of assembler dump. 
Tataa ! 

The same code debugs perfectly with FPC3.0.4.

Looks like a perfectly fine function epilogue followed by two
alignment instructions that align the next label on a 16-byte border.

But afaik the debugger is now external, and no longer integrated with
3.2 ?
