| 1 | Notes: |
|---|
| 2 | - The "destroy ...." messages below are printf()'s of the THIS pointer |
|---|
| 3 | in the wxWindowUpdateLocker::DESTROY XSUB. |
|---|
| 4 | - I could provoke this crash by simply switching files between "Main.pm" |
|---|
| 5 | (see "run script/padre lib/Padre/Wx/M*.pm" below) and another file |
|---|
| 6 | a couple of times while having syntax-check and outline view enabled |
|---|
| 7 | until the status indicator turned from an ampersand into a red |
|---|
| 8 | exclamation mark. This indicates high load. Then I waited for it |
|---|
| 9 | to go down and finally changed the file ONE more time. Crash. |
|---|
| 10 | - I dumped the SV* mentioned at the top of the backtrace. It's at the end |
|---|
| 11 | of this document. I also included the corresponding code from Wx.pm at |
|---|
| 12 | the very end. |
