           Summary: gcc -g option leaves asterisk (*) on some names to
                    assembler on HP-UX B.10.20
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: mario dot nigrovic at motorola dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: hppa2.0-hp-hpux10.20

GCC target triplet: hppa2.0-hp-hpux10.20

Here's a faulty snippit of code I got trying to compile make 3.80 with gcc 3.3.1
on an HPUX machine.  The problem seems to be that the "*" is not removed from
the function symbol name glob64:

glob64
        .PROC
        .CALLINFO FRAME=320,CALLS,SAVE_RP,SAVE_SP,ENTRY_GR=18
        .ENTRY
        stw %r2,-20(%r30)
        copy %r3,%r1
        .stabn 68,0,375,L$M17-*glob64
L$M17:

I've looked into this a bit, and it would seem that the .stabn line with the
problem is being created in .../gcc-3.3.1/gcc/config/pa/som.h, around line 39. 
I've looked at some corresponding code for other architectures and they all seem
to surround the XSTR with a call to assemble_name(FILE, XSTR ... ).  This line
is a bit curious because it ends with a "+ 1" to a string, which I assume is the
old way to get past the leading _ or other character on symbol names.

For now, I'm working around this by removing the -g from all compiles, but
that's not a great long-term solution...

I'm going to try a crack at fixing this code myself, and if I can solve the
problem, I'll add a diff or whatever to this bug report.

REPRODUCING

make exits with something like
