New issue 93 by emil.len...@gmail.com: Error backtrace not always correct http://code.google.com/p/gambas/issues/detail?id=93 1) Describe the problem. The backtrace that can be obtained by Error.Backtrace does not always contain the correct backtrace. That backtrace seems to be the current stack (not as it looked liked when the error occurred), but the frames with a greater depth than the current depth are not popped off (so if no functions are called between the error and the Error.Backtrace, everything will be ok). See example below. 2) GIVE THE FOLLOWING INFORMATIONS (if they are appropriate): Version: TRUNK Revision: r4063 Operating system: Linux Architecture: x86_64 3) Provide a little project that reproduces the bug or the crash. Public Sub PrintBacktrace() Dim s As String For Each s In Error.Backtrace Print s Next End Public Sub PrintErr() Print "An error occurred: "; Error.Text PrintBacktrace() 'Line 9 End Public Function Divide(a As Integer, b As Integer) As Integer Return a / b 'Line 12 End Public Sub run() Print Divide(1, 0) 'Line 15 End Public Sub Main() run() 'Line 18 Catch PrintErr() 'Line 20 End This will print: An error occurred: Division by zero MMain.Divide.12 MMain.PrintErr.9 MMain.Main.20 While it should be: An error occurred: Division by zero MMain.Divide.12 MMain.run.15 MMain.Main.18 The current backtrace-information (stack) should be copied when an error occurs, not during Error.Backtrace, like it is currently. 4) If your project needs a database, try to provide it, or part of it. 5) Explain clearly how to reproduce the bug or the crash. Run the example. 6) By doing that carefully, you have done 50% of the bug fix job! ------------------------------------------------------------------------------ Special Offer -- Download ArcSight Logger for FREE!
