Sounds like your system is either out of memory (and/or swap), or that
the number of Sys V shared memory segments that is configured on your
system is small.  What OS, version, distribution and CPU architecture
are you using?

If you run "make check" from the top of the GNU Radio tree, does it pass?
During the check, it allocates and frees many, many shared memory segments.
