Hi,

My question now is if there is a reason why FPC doesn't call backtrace (see
man backtrace) on Linux and Unix (including MacOS) platforms ?
It seems this is a relatively recent addition to libc, which means, after
2000. :)
program TestBacktrace;
procedure StackMe
( theDepth : integer);
begin
writeln
( 'theDepth = ', theDepth);
Dump_Stack
( stdout, 0);
writeln;
if theDepth > 1
then StackMe
( theDepth - 1)
end;
begin
writeln
( 'main program');
writeln;
StackMe
( 6)
end.
prints
main program
theDepth = 6
theDepth = 5
theDepth = 4
$00011680
theDepth = 3
$00011680
$000116C5
theDepth = 2
$00011680
$000116C5
$000116C5
theDepth = 1
$00011680
$000116C5
$000116C5
$000116C5
So, how should I call Dump_Stack ?
Also, there is no symbol information (on MacOS). Is this because of the
separate .dSYM file ?
