Unrecognized signature of debug types
« on: July 16, 2018, 11:44:14 am »
Hi there,
For some days now, I've been fighting with an odd little problem:
Code: [Select]
POLINK: warning: Unrecognized signature of debug types in object 'Tmp_File.obj'; ignored.
POLINK: warning: Unrecognized signature of debug symbols in object 'Tmp_File.obj'; ignored.
Unique object file Tmp_File.obj is assembled with MASM and /Zi /Zd /Zf
Linker commandline has /debug

Besides, sometimes polink chokes with:
Symbol '$$000000' is multiply defined: 'tmp_file.obj' and 'tmp_file.obj'

There is no such symbol in the *.lst file, and Tmp_File.obj is the only object file on the commandline.

This happens with the new polink and the version of March 15. With both of them, I can't see symbols in Olly, while polink of April 2011 shows them to me.

Any idea what could cause this trouble?

P.S.: The combi of ...
Masm 6.15 with /Zi /Zd
Polink March 2015 with /debug

... works just fine. No warnings, and symbols show up in Olly.

polink 9: M$ CodeView just ignored ?

Symbol '$$000000' is multiply defined: 'tmp_file.obj' and 'tmp_file.obj'
probably a local label ?

What ml version used ?

EDIT:
Code: [Select]
.386
.model flat, stdcall
public mainCRTStartup
.code
foo1 proc
jmp $$1
$$1:
ret
foo1 endp

foo2 proc
jmp $$1
$$1:
ret
foo2 endp

mainCRTStartup  proc
xor eax,eax
ret
mainCRTStartup endp
end mainCRTStartup
