[Trilinos-Users] Workaround for odd bug involving /usr/include/c++/4.0.0/cstdlib:110: error: '::malloc' has not been declared on OS X.4 Mac Pro

[Aron Ahmadia]

Hi Doug,

Thanks for the tip!  Fortunately this was a bug on my side, just a bit hard
to detect.

I had an improper expat lib installation (it's not installed by default in
OS X), and this was causing the malloc test to crash mysteriously, resulting
in configure deciding to replace malloc with rpl_malloc.  Later on, when
cstdlib tried to include malloc, this of course crashed because malloc was
gone.

Lesson?  I should be more careful proceeding through configuration of
scientific libraries... I will reiterate my suggestion that configure should
do a 'sanity-check' on all the configure and library options, trying to
compile them in its various ways before running its tests.  configure
blindly continuing when the malloc test failed is the absolutely the last
thing it should have done, and it deciding to replace malloc with rpl_malloc
was buried down in a configure log in triutils.

Cheers,
~Aron
