can you try

gdb.exe /*c:\sources\compiled\TestUib.Exe*/

info line *0x0040D628

The whole thing is rather odd. From what you described, you done the 
correct steps. And it works, if I do it here (vista 32 bit). Though I 
use the released fpc 2.6.0 (that may still be an idea)

I can only see 2 reasons.
1) For some reason, fpc did not write or link symbol info for your unit.
2) The stabs reader in fpc has problems reading it ("resolve" uses the 
same reader)

In case 2 gdb should be able to read it.
