[Vala] Using --enable-mem-profiler

[Robert Schroll <rschroll gmail com>]

Hi all,

I'm attempting to use --enable-mem-profiler to allow me to use 
mem_profile() in a Vala program.  However, I'm getting errors related 
to realloc() as soon as I attempt to create any new objects.  What am I 
doing wrong?

I have a simple test program (mem-test.vala):
> public int main(string[] args) {
>     stdout.printf("Running\n");
>     Object object = new Object();
>     return 0;
> }

I compile it with
> valac --enable-mem-profiler mem-test.vala
I get a warning about an unused variable (obviously), but it compiles 
just fine.  When I try to run it, though, I get
> Running
> *** Error in `./mem-test': realloc(): invalid pointer: 
> 0x00000000017d0e80 ***
> Aborted (core dumped)
Note that the print statement was able to run; the core dump occurs on 
the next line.  The program runs fine when compiled without 
--enable-mem-profiler.

I'm using valac 0.26.2 on Ubuntu 14.04.  But I see the same behavior 
with versions 0.24.0, 0.22.1, 0.20.1, 0.18.1, and 0.16.1.  Am I doing 
something wrong, or do others see this problem as well?

Thanks,
Robert
