I just tried to compile the Suse Linux package bochs-2.2.1-202
with the GNU C++ compiler version 4.4 snapshot 20080829.
The compiler said
In constructor 'bx_null_pktmover_c::bx_null_pktmover_c(const char*, const
char*, void (*)(void*, const void*, unsigned int), void*, char*)':
eth_null.cc:88: error: BB 18 can not throw but has EH edges
eth_null.cc:88: internal compiler error: verify_flow_info failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Pre-processed source code attached. Flags -O2 -fpermissive required.

}
extern int bx_pc_system;
