Package: lazarus-ide-2.2
Version: 2.2.6+dfsg2-2+b1
Severity: important
X-Debbugs-Cc: p...@jbechtel.de
Dear maintainers,
I recently wanted to start a little notekeeping program in Free Pascal (Object
Pascal) but was very quickly stopped by gdb not working.
After some search for the problem I found that the array initialization was the
problem, actually following line:
var scopes: Array of integer = (); // <-- this line causes the crash
Following conditions have to be met to reproduce the problem:
* The line must be in an extra unit (not application form class unit)
* gdb 13 must be installed (gdb 10 does not crash)
After the system information I copy the most important code files and the last
part of debug log.
It is basically a new graphical project with an extra unit.
I have set Severity to "important" because intermediately I was thinking that
dynamic arrays are not allowed in fpc Object Pascal which was irritating. When
installing gdb 10, however, world looks different.
Feel free to ask for details. Please don't mind high reaction times.
Best regards
Jonas Bechtel
