Balsa hanging, error located but not fixed

[Julian M Catchen <julian catchen org>]

Ok, a few weeks ago, I zipped up what looked like a normal message and sent
it to this list, asking if anyone could verify if it displayed correctly. 
For me, it was causing Balsa to totally hang.

A few people responded and said that it worked fine.  So, I deleted it and
didn't worry about it (although it continued to make balsa hang for me).  
Now, I have found a second email today that did the same thing.  Perfectly
normal email, causes balsa to totally hang.  So, I ran it through gdb and
found
that it is entering into an infinite loop at the following place:
    
src/quote_color.c, line 77  while (regexec(rex, str + off, 1, rm, 0) == 0)
{

The call to the function, regexec(rex, str + off, 1, rm, 0), was never
returning.  
It was choking on this line of text from the message:

################################################################################

Here is my regular expression: ^(([ \t]|)*[|>:}#])+

When I change my regular expression to this: ^(([ \t]|)*[|>:}])+  it works
fine.

So, the question is, is this a bug?  Or, is it my fault for having a funky
regular expression?

Thanks,

julian
