           Summary: g++ generates wrong line numbers on solaris/gdb
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P2
         Component: debug
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: dhazeghi at yahoo dot com
                CC: gcc-bugs at gcc dot gnu dot org
GCC target triplet: sparc-sun-solaris2.8

See bug 7360 for more details.

Symptom is seen by:
bash-2.05b$ g++ -g test.cxx classes.cxx -o test
bash-2.05b$ gdb test

This GDB was configured as "sparc-sun-solaris2.8"...
(gdb) list D
Line number 20 out of range; classes.cxx has 5 lines.

Clearly there is no such line, and equally clearly, D isn't on it.

testcase including sources and crashing binary

Oh I forgot to mention that this occurs with gdb 5.3. Haven't tested newer.

Confirmed on 3.3 branch and mainline (with GDB 5.3 and GDB 6.0).

GCC 2.95.3 gives "Line number 23 out of range; classes.cxx has 5 lines."

Fixed by the switch to DWARF-2 as the default debugging format.  The problem
still affects g++ on Solaris 2.5.1 and 2.6 though, because it still use STABS there.

Given that the STABS support has already started to bitrot, I'm closing the bug.
