FYI: Laz trunk: could not find abbrev number 110

Just FYI (I'm probably using too new a debugger):

Regular debug settings (automatic, line numbers)

Lazarus trunk, FPC x64 trunk, GNU gdb (GDB) 7.3.50.20110510-cvs,
Windows 7: with the attached project, with one breakpoint set, I get:

Code: [Select]Failed to load file: Dwarf Error: Could not find abbrev
number 110 [in module
D:/Reinier/Documents/SourceCode/fpc_laz_patch_playground/dbftool.exe]

When doing the same under Laz x86 trunk, FPC trunk, GNU gdb (GDB)
7.3.50.20110510-cvs, I get the dbftool has stopped working, close or
debug Windows crash dialog window

Debugging works fine with Laz 1.0.10/FPC 2.6.2 and released debugger.

AFAIR, there were some changes in dwarf generation recently in FPC:
http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/compiler/dbgdwarf.p
as?r1=25054&r2=25053&pathrev=25054
... don't know if that has anything to do with it.

Thanks Martin, yes, that seems like a likely cause. Hope it gets fixed
soon
