            Bug ID: 17815
           Summary: Make fields of self case-insensitive like other pascal
                    variables
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: pascal

Example source code

In the pascal parser, there is special code
that will try to emulate case-insensivity despite the
fact that pascal is not registered as a 'case-insensitive' language.

# Compile attached source code, using Free Pascal compiler

fpc -gs -Mobjfpc test-class-pascal.pas

# Debug it
gdb ./test-class-pascal
.......
(gdb) b TA__CHECK
Breakpoint 1 at 0x40154c: file test-class-pascal.pas, line 23.
(gdb) r
Starting program: E:\pas\test\test-class-pascal.exe
[New Thread 6700.0x1ae0]

Breakpoint 1, TA__CHECK (B=0x1572ee0, this=<error reading variable>)
    at test-class-pascal.pas:23
23        check:=(x < b.x);
(gdb) p this
$1 = (TA) 0x1572ed0
(gdb) p this^
warning: can't find linker symbol for virtual table for `TA' value
$2 = {<TOBJECT> = {_vptr$ = {0x408014, 0x43}}, X = 67, Y = 33}
(gdb) p X

Type TA has no component named x.
