Martin Schreiber wrote: How can we identify a dynamic array with FPC dwarf? You can't, and ideally this shouldn't even be necessary. In the past years, people have implemented support in GDB for Fortran and ADA arrays that also have dynamic length counts. We should update our DWARF code to properly describe the dynamic length location too, so GDB will automatically do the right thing (to be enabled/disabled via a -gXXX command line option, so the old method can still be selected for use with older GDB versions).

Confirmed with Linux x64 gdb 7.9.1. gdb with FPC -gw3 crashes by many watches
("self",arrays,pointers...) and does not find uppercase queries for lowercase
variables so the workaround for class variables can not be used. It is
completely unusable for IDE purpose.
