2.95.2: exception handling - some missing!

[Dr. David Gilbert]

Hi,
  I have a problem with gcc 2.95.2 and C++ exceptions. Exceptions
are not being caught; looking at the generated assembler it appears that
there are a very small number (<1%) of the exception blocks
(.LEHB/.LEHE) which aren't ending up in the exception table.  This is a
BIG source file with LOTS of catch blocks (around 5K blocks) (it is
generated by the SWIG tool) and actually while this has been a problem for
a while we haven't hit it because only now has it landed on a block which
actually caused an exception.

  That was compiling with either -O1 or -O2; no -O flag gives all OK.

Is this a known problem? If so is there a known fix or something to avoid
doing (other than exceptions!).

Thanks a lot,

Dave
