[osg-users] Crash on Mac OS X

[Robert Osfield]

Hi Ale,

I don't have an answer but do have a vague recollection that in certain
compiler options problems have been reported with dynamic_cast<>.  My gut
says it was OSX in some combination.  It may well be a bug in the compile,
try out gcc instead of Clang.

Sorry I can't be more specific, I don't have OSX system to test against and
my vague recollections of something related to dynamic_cast<> is down to
reading about the issue quite some time ago, just reading through, I wasn't
an active participant in the discussion.  Searching through the
osg-users/forum archive might help, as would a general search of the web on
the issue.

Robert
