Segmentation fault while linking shared library

[Alan Krause]

Binary package hint: binutils

The last version of Ubuntu which successfully compiled a 64 bit shared library (compiler used is free pascal) was 8.04. Ever since binutils has been ubgraded to 2.19.1, I am no longer able to do so due to a segmentation fault in the linker.

To reproduce the problem, do the following:

1. Create and save a file named proj.pas, with the following contents:

library project1;

uses
 Classes;

function dRound(iDec: integer; dRate: double): double;
const
 TenToPower: Array[0..9] of integer = (1, 10, 100, 1000, 10000, 100000,
                                       1000000, 10000000, 100000000, 1000000000);
var
 dInc : double;
begin
 if iDec > 0 then begin
    dInc := 0.5000001;
    result := trunc (dRate * (TenToPower [iDec]) + dInc) /
       TenToPower [iDec];
 end else begin
    result := dRate;
 end ;
end;

function one : double; cdecl;
begin
 Result := dRound( 2, 0.529 ) ;
end;

begin
end.

2. Compile (but not link) the source code using free pascal (v2.2.4):
fpc -Sd -Cg -Cn -O3 proj.pas

3. Attempt to link the shared library using the generated ppas.sh script:
./ppas.sh

Here is the output I receive:

Linking libproj.so
Segmentation fault
An error occurred while linking libproj.so

Just a quick update - the same problem happens for i386.

fixed in karmic, binutils 2.19.51.x
