This is a followup to
https://www.cygwin.com/ml/cygwin/2015-10/msg00059.html .
I tried to build icu using gcc-5 and binutils-2.25-2 on x86. The build
appeared to hang when cygport was stripping executables. I traced the
problem to a call to 'nm -l' in src_postinst.cygpart. This produced
errors like the following when called on some of the DLLs:
$ nm -l cygicui18n56.dll
6270c458 b .bssBFD: Dwarf Error: Could not find abbrev number 1151.
6270c594 b .bssBFD: Dwarf Error: Could not find abbrev number 1151.
6270c0cc b .bssBFD: Dwarf Error: Could not find abbrev number 1151.
...
This particular DLL can be found at
http://sanibeltranquility.com/cygwin/cygicui18n56.dll.xz
nm -l from binutils-2.25-1 has no problem on this DLL. The behavior is
the same whether the DLL is built using binutils-2.25-1 or 2.25-2, so
this appears to just be a bug in nm. [The DLL I posted at the above URL
was buil with binutils-2.25-1.]

Hi Ken,
Are you able to reproduce a test case? Seems to require some complexity
to trigger it.

Actually, it turns out to be quite easy to trigger it. I just tested
random programs that were sitting around, and here's the smallest one I
found that exhibited the problem:
$ cat getcwd.c
#include <limits.h>
#include <unistd.h>
int
main ()
{
char buf[PATH_MAX];
getcwd (buf, PATH_MAX);
}
$ gcc getcwd.c
$ nm -l a.exe
00406000 b .bssBFD: Dwarf Error: Could not find abbrev number 120.
00406018 b .bssBFD: Dwarf Error: Could not find abbrev number 120.

00406040 b _u.25303BFD: Dwarf Error: Could not find abbrev number 120.

Kai is of the opinion that rebuilding the gcc, CRT, Cygwin and
everything in between be rebuilt with the new binutils to solve the issue.
Might be a huge undertaking.

That depends on what you mean by "everything in between". Wouldn't it
suffice to rebuild the cygwin package and the toolchain?
The main issue for us, AFAICT, is that package maintainers need to be
able to build their packages without having the build take hours when
cygport calls 'nm -l'.

I'll be rebuilding the CRT and cygwin gcc soon to give this a try.

Nope, rebuilding the crt and Cygwin dll did not help at all.

Updating binutils against git master seems to have solved the problem,
so new binutils version incoming.

Didn't know it was also happening on 64bit, I will update it soon.

I will appreciate.
I built 2.25-4 for x86_64 using the x86 source and this
problem seems gone.
$ nm -l liboctave/.libs/cygoctave-3.dll |& grep Error
produces no any more Dwarf complains.
PS:
Not sure if it is relevant for your build, but I noticed:
checking for version 0.10 of ISL... no
checking for version 0.11 of ISL... no
