Summary: Stack corruption with C++ exceptions

Initial Comment:
OS: Windows 2000
gcc version 3.4.0 (mingw special)
GNU ld version 2.13.90 20021005
cygwin build environment
mingw runtime version: 3.3
w32 api version: 2.5

I observe stack corruption when catching exceptions in
functions using variable sized arrays. 

I have attached a test case: When compiled with 

g++ test.cc 

and executed, the program fails in the assertion after
catching the exception. If the throw is uncommented,
the assertion holds. If the array declaration is
changed to have a fixed size (i.e. replace int a[size]
with int a[2]), the assertion also holds.

I have observed the same problem with gcc 3.3.3. I have
not been able to reproduce this under Linux.
