There are bugs in the VLA support in 3.4.x, fixed in GCC 4.0, but not feasible
for backporting.  Furthermore, in your testcase the use of VLAs in arguments
is completely useless.

Thank you. We will change the code to remove VLA. However, we had successfully
compiled this code under 3.2 and obtained some results(These are time consuming
calculations). Now, should we trust those results? 
Please accept our apology if we are not supposed to ask such questions here.
