Details:

Hello,
it looks like there is something wrong with the handling of
the arguments
after the sentinel of a vararg method implemented through a
pinvoke.
I attach an executable that shows the bug (test.exe), along
with a dynamic
library required (gcc4net.dll).
The executable was produced by CIL port of GCC (see
https://gna.org/proj
ects/cil4gcc) and not with pnet C compiler, this is why
I
attached the binaries.
Never mind how it was produced, it is valid CIL, and it
should run correctly
with ilrun.
Instead, a wrong number is printed after "foo"
in the program output.

The source code of the test is:

int printf (const char*,...)
__attribute__((pinvoke("/lib/libc.so.6")));

int main()
{
    printf("foo %d \n", 3);
    return 0;
}
