[Metakit] Compiling on Sparc Solaris 8 w/ CC and MetaKit 2.4.8

[Dan Gregory]

Has anyone tried to compile this package with CC, specifically(Sun WorkShop 6 update 1 C++ 5.2 Patch 109508-09 2002/07/08)?   The symptoms I was getting are:  I can compile ok, but the test cores on b14(actually running in the debugger can get it to run correctly) when the view is accessed via GetAs().  This tries to invoke ~c4_string and when it dereferences p, it cores.  If are having this problem then you can replace this method:

const char* c4_HandlerSeq::Description()
{
  return _field != 0 ? UseTempBuffer(Definition().DescribeSubFields()) : 0;
}

with this one:

const char* c4_HandlerSeq::Description()
{
  const char* returnPtr = (_field != 0) ? UseTempBuffer(Definition().DescribeSubFields()) : 0;

  return returnPtr;
}


I think the problem lies somewhere with the destruction of temporary variables.  The temporary c4_String variable returned from DescribeSubFields get descructed before Definition() or DescribeSubFields() gets called.  It seems totally hosed...  I am in the process of discussing this with sun to see if it's a bug or not.


Later,
Dan
