addr2line on aix not correctly following #line

[Brendan Doherty]

Hi, 

We are using addr2line to produce a stacktrace from
programs when an error occurs.  These programs have
been converted from another language to c++, and make
frequent use of #line to map the c++ lines back to the
original source code.  

When addr2line is reporting the filename:line number,
it is only following the line number from the #line
statement, and not the filename.
As an example, if a stack trace was generated from
line 4 of MYFUNC.cpp, addr2line would report
MYFUNC.cpp:2, where as gdb 6.0 would report
MYFUNC.xxx:2.  addr2line is partly working, as it has
given the correct line number.

MYFUNC.cpp:
#include <myinclude.h>
void MYFUNC() {
#line 2 MYFUNC.xxx
    crashhere();
}

We are using binutils-2.14, gcc-3.3.2, gdb-6.0.  If
you have any ideas, or patches, that might fix this
issue, please let me know.

Brendan
