This is certainly some corner case bug that is camping out, waiting
to activate under specific rare conditions.  Otherwise why would
adding one more element cause the crash?  Probably the reason it
crashes on one machine and not another is related to specific
memory layout used by the program, which depends on exact compiler
version as well as exact library versions in use.

I doubt we can say anything else useful about the cause of this bug
except that it is a data-dependent, rarely occurring, corner case
bug in pcb.  Can we figure out what the other argument to
strcmp() is?  Maybe add a printf() to find_element_by_refdes in
action.c:6944 ... it is probably a null pointer.

Probably not since the “L” prefix is only a compile-time aspect of
C/C++ and has nothing to do with runtime strings.
