http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47022 --- Comment #5 from Jakub Jelinek jakub at gcc dot gnu.org 2010-12-31 11:01:05 UTC --- Created attachment 22874 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=22874 gcc46-pr47022.patch I think we can either handle the bunch of missing types in tsubst_copy as done in this patch, or in the default: case of tsubst_copy if t is a type just call tsubst instead of gcc_unreachable, or call tsubst instead of tsubst_copy on the second argument of VA_ARG_EXPR (which is a type, not expression), or any combination of these.

I found this code ICEs:
#include stdarg.h
templatetypename _T
void foo(_T *p, va_list argptr)
{
*p = va_arg(argptr, long double); //float/double
}
void bar(va_list ap)
{
long double argdata = 0;
foolong double(argdata, ap);
}
Changing long double to double or float also causes the ICE
but this is OK:
#include stdarg.h
templatetypename _T
void foo(_T *p, va_list argptr)
{
*p = va_arg(argptr, _T);
}
void bar(va_list ap)
{
long double argdata = 0;
foolong double(argdata, ap);
}
