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

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

00406018 b .bssBFD: Dwarf Error: Could not find abbrev number 120.
