Memory Corruption Issue??

[Bottled Gin via Digitalmars-d]

Greetings

I am struggling with strange memory corruption issues with 
dmd-2.069.2 release.

The issue shows up only when I load a shared library created from 
D code from C and call some D functions from the C side. But 
since the program control is completely with the D code, and data 
structures in D get corrupted, I believe C has no role to play in 
the corruption. It is just that the memory layout of the 
executable, when the compiled D code is loaded from C, is helping 
in replicating the issue.

I have spent almost a week in reducing this issue to less than 
100 lines of code. Now I need the developers' love and help to 
get this issue fixed. There is some bleak chance that I am doing 
something wrong while loading the D library from C code. But 
otherwise it looks like a DMD memory corruption issue.

Since two C, and one D files are involved in recreating the 
issue, I have put all the files on a github repository along with 
a makefile. I have been able to recreate the issue on two Ubuntu 
14.04 64-bit machines.

Generally the issue seems to be with static (thread local) 
variables that get allocated on heap. If I create many such 
variables, I get data corruption in some of these variables and 
sometimes I get segmentation fault. In this testcase that I have 
reduced, contents of a dynamic array are getting corrupted. Since 
all the data is being accessed from only one thread, there is no 
chance of a multicore race condition.

To reproduce the issue, kindly clone my git repo 
(https://github.com/puneet/memerr.git). Change the path of the 
DMD installation (I have tested only with dmd-2.069.2) in the 
makefile and run make.

$ git clone https://github.com/puneet/memerr.git
# change DMD install path in memerr/makefile
$ make

I get an output like:

$ make
/home/puneet/local/dmd-2.069.2/linux/bin64/rdmd foo.d
Start frop from D
Successfully completed loop....
./main
Start frop from C
0 -> @�+----------------

The last line is the content of an array which is actually filled 
with only dashes in the code.

Kindly help. I want to make sure that I am not making a mistake 
before I file a bug on dlang bugzilla.
