            Bug ID: 17433
           Summary: ld crashes with segmentation fault when linking with
                    libmpir.a
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: dan at math dot uiuc.edu

ld crashes with segmentation fault when linking with libmpir.a

To reproduce:

    wget http://mpir.org/mpir-2.6.0.tar.bz2
    tar xjf mpir-2.6.0.tar.bz2
    cd mpir-2.6.0
    ./configure --build=x86_64-pc-cygwin
    make
    ld -u __gmpn_gcdext .libs/libmpir.a

Since gdb doesn't show me any useful information (the stack is destroyed), 
it's hard to tell whether this is a cygwin problem or an ld problem, as it
doesn't
happen under Mac OS X or under several flavors of linux.

I reported it to the cygwin mailing list, but no one seems interested in it.

The output from cygcheck -s -v -r is too large to attach here.

The consequence of the bug for us is that Macaulay2 (see http://macaulay2.com/)
will not compile under cygwin.  I think I can make it work by using GMP
instead of MPIR, but I'd prefer "ld" to work.
