Here are the details that you ask for:

* The GMP version number, and if pre-packaged or patched then say so.

GMP 5.0.2. Only modification is to use libtool 2.4.2. (See the message
"gmp fails to configure when I pass --host" for the recipe.)

* A test program that makes it possible for us to reproduce the bug.
  Include instructions on how to run the program.

The test programs are tests/mpz/reuse and tests/mpz/t-root, generated
in the build tree by running "make" in gmp-5.0.2.

The programs are run through
  $ cd tests/mpz; make check TESTS="reuse t-root"

* A description of what is wrong. If the results are incorrect, in what way.
  If you get a crash, say so.

The messages "GNU MP assertion failed" indicate an assertion failure,
that calls abort().

* If you get a crash, include a stack backtrace from the debugger if it's
  informative (`where' in gdb, or `$C' in adb).

* Please do not send core dumps, executables or straces.

* The configuration options you used when building GMP, if any.

Configured with options
  '--prefix=/home/haible/prefix-linux-sparc32' 'NM=nm' 'ABI=32' 'CPPFLAGS=-Wall'

* The name of the compiler and its version. For gcc, get the version with
  `gcc -v', otherwise perhaps `what `which cc`', or similar.

$ gcc -v

* The output from running `./config.guess', and from running
  `./configfsf.guess' (might be the same).

The latter file is not executable.

$ ./config.guess

$ sh ./configfsf.guess

* If the bug is related to `configure', then the compressed contents of
  config.log.

It is most probably not related to configure.

* If the bug is related to an asm file not assembling, then the contents
 of config.m4 and the offending line or lines from the temporary
 mpn/tmp-<file>.s.

N/A
