There are incompabilities in exception handling between gcc and icc.
They might exist between different gcc versions, too.
Those incompabilities become apparent when a program loads a shared
library which in turn uses another shared library and those libraries
and the main program have been compiled using different compilers (e.g.
main program and libboost_python.so with icc, python with gcc). In that
situation, passing an exception from the the second shared library
through the first library to the main program can lead to crashes. (It
took us some time to figure that out.)
