>Description:

Trying to build devel/boost-libs on sparc64 -current breaks with an internal
gcc compiler error:

ore was generated by `cc1plus'.
Program terminated with signal 4, Illegal instruction.
#0 0x00000000001ba7a0 in gt_ggc_mx_lang_tree_node ()

Note that the compile uses g++ -O3.

However, it is not clear to me why it gets a signal:

Nothing illegal in this instructions, AFAICT, but %fp looks bogus:

I patched the boost-libs build and see different (but alike) failures
with -O2.

It works with -O1.

it seems the compiler error is gone on modern boost-libs but now
there is missing "context" (ucontext(2)?) support for sparc*.
it ends up chosing an "unsupported.cpp" from
libs/context/build/Jamfile.v2.

Oliver asked me to take a look at it again after optimzations, but at that
time pkgsrc jam was too old - I'll check again now.

Guess this PR should be closed.
