c++ - Linker error - not enough characters in symbol resolution??

I get the following when trying to link one of the STLSoft unit-test programs. I'm guessing that there aren't enough symbols used to discriminate between records, but it's all conjecture. (Am using DMC++ 8.44 b3, btw; also happens with 8.43) Cheers Matthew link -DELEXECUTABLE -NOLOGO .\stlsoft.unittest.obj+.\stlsoft.unittest.0.obj+.\stlsoft.unittest.1.obj+.\stlsoft.unittest.2.obj+.\stlsoft.unittest.3.obj+.\stlsoft .unittest.4.obj+.\stlsoft.unittest.5.obj+.\stlsoft.unittest.6.obj+.\stlsoft.unittest.7.obj+.\stlsoft.unittest.8.obj+.\stlsoft.unittest.9.obj+.\stlsoft.unittest. 10.obj+.\stlsoft.unittest.11.obj,"..\..\bin\stlsoft.unittest.dm.stlsof .exe",,kernel32.lib ..\..\lib\stlsoft.unittest.dm.lib kernel32.lib OPTLINK (R) for Win32 Release 7.50B1 Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved .\stlsoft.unittest.1.obj(stlsoft.unittest.1) Offset 015DCH Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$new_allocator stlsoft H 1 $0BA stlsoft SAAAV?$new_allocator stlsoft H 3 XZ23 4V43 A .\stlsoft.unittest.3.obj(stlsoft.unittest.3) Offset 01E50H Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$new_allocator stlsoft H 1 $0BA stlsoft SAAAV?$new_allocator stlsoft H 3 XZ23 4V43 A .\stlsoft.unittest.4.obj(stlsoft.unittest.4) Offset 01B08H Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$new_allocator stlsoft H 1 $0BA stlsoft SAAAV?$new_allocator stlsoft H 3 XZ23 4V43 A .\stlsoft.unittest.5.obj(stlsoft.unittest.5) Offset 018D5H Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$new_allocator stlsoft H 1 $0BA stlsoft SAAAV?$new_allocator stlsoft H 3 XZ23 4V43 A .\stlsoft.unittest.6.obj(stlsoft.unittest.6) Offset 019CAH Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$new_allocator stlsoft H 1 $0BA stlsoft SAAAV?$new_allocator stlsoft H 3 XZ23 4V43 A .\stlsoft.unittest.7.obj(stlsoft.unittest.7) Offset 01BCDH Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$new_allocator stlsoft H 1 $0BA stlsoft SAAAV?$new_allocator stlsoft H 3 XZ23 4V43 A .\stlsoft.unittest.8.obj(stlsoft.unittest.8) Offset 01A20H Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$new_allocator stlsoft H 1 $0BA stlsoft SAAAV?$new_allocator stlsoft H 3 XZ23 4V43 A .\stlsoft.unittest.8.obj(stlsoft.unittest.8) Offset 01F19H Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$malloc_alloca or stlsoft H 1 $0EA (unsigned char ?1??get_allo cator::H::stlsoft::HV?$malloc_allocator::lsoft::auto_buffer<>::?1??get_allocator::s_allocator) .\stlsoft.unittest.9.obj(stlsoft.unittest.9) Offset 024B7H Record Type 0091 Error 1: Previous Definition Different : ?s_allocator ?1??get_allocator ?$auto_buffer stlsoft HV?$new_allocator stlsoft H 1 $0BA stlsoft SAAAV?$new_allocator stlsoft H 3 XZ23 4V43 A

Of course that's what it means. That's obviously not where the problem lies. What I'm saying is that it's wrong, or to be more precise: either the linker is correctly detecting that the compiler is making multiple instances of something for which there should only be one, or that the linker is not correctly coallescing multiple definitions into one, as dictated by the language inlining rules. And the confidence with which I say this, and made the original post, over and above the fact that I'm doing something C++-sensible is that about 16 other compilers compile and link an executable from the same sources successfully. Anyway, I've found a workaround now. Just one more #ifdef STLSOFT_COMPILER_IS_DMC ... ;-(I get the following when trying to link one of the STLSoft unit-test programs.
