Ok... I may have found the problem - unfortunately the issue now puts
the whole ksh93-integration putback in danger:
It seems the problem is triggered by the C99 feature to dynamically size
arrays on the stack.
Example:
In C99 (and C++) the following code is valid:
-- snip --
void foo(int size)
{
int myarray[size];
/* more core comes here */
}
-- snip --
Adding this construct to any C code in the OS/Net codebase causes the
CTF tools to fail like described above.
Another example is:
-- snip --
/opt/SUNWspro/bin/cc -O -K pic -xspace -Xa -xildoff -errtags=yes
-errwarn=%all -erroff=E_EMPTY_TRANSLATION_UNIT
-erroff=E_STATEMENT_NOT_REACHED -erroff=E_UNRECOGNIZED_PRAGMA_IGNORED

It seems this issue crept in either between B37 and B48 or between B48
and B51... ;-(
