Something like this (from test_vmcircbuf)?

Testing gr_vmcircbuf_mmap_shm_open_factory...
....... gr_vmcircbuf_mmap_shm_open_factory: Failed
gr_vmcircbuf_factory::test_factory (gr_vmcircbuf_mmap_shm_open_factory): caught 
SIGBUS


BTW, I have strange segfaults with "make check" in test_all:

Program received signal SIGSEGV, Segmentation fault.

My system is Debian with kernel 2.6.9-1-k7 and gcc-3.4 (GCC) 3.4.2
(Debian 3.4.2-3), gnuradio-core configure'd with --disable-static.

Could it be possible to add the test for the broken toolchain in
configure.ac ? What the symptoms are like?
