Maybe "blub" was interpreted as "char[5]" or "char const *" instead of 
"char *".  At least the first alternate choice is incompatible with 
"char *" as far as exception type matching is concerned.  (The C family 
of languages is broken in that it treats arrays as pointers with funny 
settings.  And even that breakage is broken because it uses that 
treatment only 90% of the time; the other 10% of uses treat arrays and 
pointers differently [e.g. extern], and you probably found one of them.)
