Vincent did some tests with dwarf on win 64 bit.
with the lates (7.2.5) gdb and trunk results are fine => working.
but with fpc 2.4.2 instead there are strange errors:
> 84. <info address FPC_BREAK_ERROR>
> 85. &"info address FPC_BREAK_ERROR\n"
> 86. ~"Symbol \"FPC_BREAK_ERROR\" is at 0x10000f330 in a
> file compiled without debugging.\n"
> 87. ^done
> 88. (gdb)
> 89. <-break-insert *4295029552>
> 90. ^error,msg="Dwarf Error: Cannot find DIE at 0x23c8de
> referenced from DIE at 0xef [in module
> 91. (gdb)
As you can see the correct address is returned => but attempting to use
it to insert a breakpoint (it is the same addr, only decimal) => gets a
very strange error.
Exactly the same commands do work, if the exe was compiled with fpc trunk
