On win 32 there is currently a choice between:
- gdb 7.2 (or older)
does not have
http://sourceware.org/bugzilla/show_bug.cgi?id=14018 which means the debug session can be lost at any time.
all later versions have this issue.
- gdb 7.3 (which has both known issues...)
- gdb 7.4 / 7.5
which can set environment vars for the debuggee
http://sourceware.org/bugzilla/show_bug.cgi?id=10989There is also an error with stepping, if a library is unloaded (or maybe it is a thread being closed). It was observed with 7.4 and 7.5. But as it is not reproducible, it is not known, if it will occur with earlier versions.
If encountered, the IDE will display a gdb message about being unable to set a breakpoint with a negative number.
Otherwise, all Lazarus debugging abilities seem to run equally good on 7.2 and 7.4/7.5
This should affect all win32 snapshots from tomorrow (including "fixes branch"), and all future releases.
Given the choice I decided to go back to 7.2. Since the stability affects everyone.
If you need environment, then please keep a copy of 7.4. (All IDE changes are usually tested for all gdb 7.x versions)
If you encounter other issues please mail.
