Your suggestion  is a workarround. The other one is to turn the static library 
to dynamic one.

Static libraries should only be linked with the executable. Shared objects are

Er, I don't know about shared global data segments, but in this thread there is 
no mention of crossing the process boundary, only merging 2 variables in a given 
process.
