  errbld.cpp: In method `a::a()':
  errbld.cpp:25: Internal compiler error in `find_function_data', at function.c:542
  Please submit a full bug report.

It appears that trying to throw an object whose constructor
contains an array to be allocated is creating some problems
for gcc.

Other fail messages can be coaxed by altering the source 
slightly.  Another error that I got was 

  Internal compiler error in `find_function_data', at function.c:542

if you take away the inline definition for the constructor 
in class b.

I don't have a copy of the standard, so I can't say whether
the code is 100% legal, but the compiler should spit out
legitimate parsing errors if it encounters any non-kosher
code.
>How-To-Repeat:
use the following command line to compile the source:

  g++ -v --save-temps errbld.cpp
