Yes, that's what I figured, thanks!

No, all the expressions were nested pretty deeply. But there were some
"try ... with Not_found -> ..." nested there, so I am guessing one of
them was causing the exception to be caught and re-raised...
Anyway, once I cleaned the code a bit, the weirdness went away. Now the
only remaining weirdness that I see is that the innermost frame is
missing from backtrace when the exception was raised from C - PR #2030;
this one however is common to both 3.06 and 3.07+13 CVS.
