[fpc-pascal] Bug in RTL for arm

2006-02-19 Thread Koenraad Lelong

Hi,
Today I did an update via svn. When I compiled for arm (in the hope that 
the bug I encountered a while ago would have disappeared) I found a bug 
in rtl/linux/arm/sysnr.inc :

Const
 syscall_nr_base = syscall_nr_base;
I modified this to :
Const
 syscall_nr_base = $90;
which is similar to fpc 2.0.2. When I compiled this I got my ususal error :

Internalerror numbers are just unique numbers be using . 
They

don't have any meaning.

Quick intro for debugging this.
- Build compiler with debug info: 'make cycle OPT=-gl'
- Compile source with this new compiler in gdb:
   - gdb --args  
   - (gdb) br INTERNALERROR
   - (gdb) dir 
   - (gdb) r
   - Hit breakpoint
   - (gdb) bt
   - The backtrace will give you more info. Use 'fr ' to jump to
a function in the callstack so you can watch the code and variables.

OK, I tried this, but that's as far as I can get. Enclosed the output of 
the backtrace (first lines are the commandline I used).

Anything I can do further ?
Thanks,
Koenraad Lelong.
