"written length does not match optimized length" with stabs enabled

[jlawson-yasm@…]

I've encountered this internal error when attempting to compile some source code with stabs 
debugging output enabled. 
 
INTERNAL ERROR at libyasm/bytecode.c, line 839: written length does not match optimized 
length 
Abort 
 
I am using a current CVS checkout dated today (20031019).  Command-line used was:   
 
yasm -f elf -m amd64 -p nasm -r nasm -g stabs plat/x86_64/x86ident.asm

Removing "-g stabs" from the command-line allows the assembly to succeed without problems.

This is a stabs bug.  Taking ownership.

Broken Fix in modules/dbgfmt/stabs/stabs-dbgfmt.c r1.5.  Only saving for
compatibility with the previous incorrect design in case we find cases where the
stabs n_value field is not 32 bits.

Fixed in modules/dbgfmts/stabs/stabs-dbgfmt.c r1.6 by removing 16-byte stab
support.  Apparently existing 64-bit systems use truncated 32-bit n_value
fields, and objdump -G appears to agree.  stabs-dbgfmt.c now matches this behavior.

Thanks, Jeff!  Your code should now work with stabs.  (As much as the stabs
debugging works, anyway.)
