Work fine


Fri 21 Jul 2006 01:40:22 PM UTC, original submission:  

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/projects/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;
