It appears to me that this is a problem with the environment solar provides
to the shell script, and the included version of libintl chokes on
something about it (the value of $LC_IDENTIFICATION?).  You've tried
several different versions of bash, and they all seem to fail inside
libintl.

Without knowing more about the data in the stack traceback, like the
values passed to strlen, it's hard to say more.  It might be an
interaction between libc and the version of libintl included with bash;
it might be that libc isn't calling out to the bash libintl at all.
