Hi Richard, that looks like the same problem Martin, Michael and myself are experiencing. A backtrace (type "bt" in gdb) would show if this is really the case. A workaround is according to Michael to add -fno-expensive-optimizations to the compiler flags. Martin mailed another workaround for this problem (see his email with subject "[Patch]: latest egcs + mule") and contacted the egcs developers. Until they fix egcs (it seems to be a bug in egcs), you've to use one of the workarounds. There's nothing else that can be done AFAIK at the moment (except fixing egcs;-).
