However the below in NOT related to this.

This is a bug in GDB. Though there may (on may not) be an additional bug 
in either fpc, or the linker, leading to invalid debug info.
Try stabs versus dwarf. This may help. Though stabs have some extra 
limits. (see link above)


GDB 5.9/ 6.0 and 6.1 (not yet tested 6.2 but likely too) are 
particularly unstable according to my tests. So you should use an 
earlier one.

Note: trying to show resourcestrings is one known condition that will 
crash a lot of gdb versions.
