Thank you for looking into that. I'm still not done with fixing the test
suite on Solaris, but form ~70 broken tests I'm at 28. Mostly it's
because Solaris is trying to be posix correct while Linux does not.

There was one surprise though:

A='12\n34'
echo $A

prints two lines on Solaris bug only one line on Linux ('\n' is not
interpreted). That breaks most of json tests as they contain '\n').

Anyway once I'm done I'll have another patch.
