Description Sean Dilda 2004-02-03 13:32:36 EST

When using fc1-test1 for x86_64, I receive an ' error: incompatible
types in assignment' from gcc when I try to assign the value of one
va_list variable to another.  This does not happen on an x86 box
running fc1.

Attached is a small test case that does nothing useful, but it will
error if you try to compile it on x86_64, but not on x86.

That testcase is buggy, you cannot do that.
If you need to copy va_list objects, you need to use va_copy.
See man va_copy for example, or ISO C.
