[Mingw-users] possible regression in gdb 7.4 with -break-insert +0

[Martin]

I believe I found a regression in gdb 7.4. (Tested on Win 32bit Vista)

If indeed it is, I am unsure how to report. Also I can not provide
sample code (except in pascal, using fpc)

using "gdb -i mi", the command "-break-insert +0" should insert a
breakpoint at the an offset of 0 lines from current.

With previous versions of gdb, if the command was issued before
-exec-run, then a breakpoint was inserted at the first line of code.

Using gdb 7.3-2
-break-insert +0
^done,bkpt={number="2",type="breakpoint",disp="keep",enabled="y",addr="0x00402f64",func="main",file="WatchesPrg.pas",fullname="b:\\lazarus_latest\\debugger\\test\\gdbmi\\testapps\\watchesprg.pas",line="269",times="0",original-location="WatchesPrg.pas:269"}
(gdb)

Using gdb 7.4-2
-break-insert +0
^done,bkpt={number="2",type="breakpoint",disp="keep",enabled="y",addr="0x00402f64",func="main",file="WatchesPrg.pas",fullname="b:\\lazarus_latest\\debugger\\test\\gdbmi\\TestApps\\WatchesPrg.pas",line="269",times="0",original-location="WatchesPrg.pas:+0"}
(gdb)

and then
-exec-run
....
&"Error in re-setting breakpoint 2: No line 0 in file \"WatchesPrg.pas\".\n"
=breakpoint-modified,bkpt={number="2",type="breakpoint",disp="keep",enabled="n",addr="<PENDING>",pending="WatchesPrg.pas:+0",times="0",original-location="WatchesPrg.pas:+0"}

Please report it here:

g...@sourceware.org

And don't worry about the example in Pascal, just post it. At least
one of the active contributors to GDB (and to its Windows port) uses
fpc, so you are not alone.

Thanks.
