I modified pdksh (from version 3.3 of freeBSD ), compiled it (with
the -g option) and placed a breakpoint at c_print (the entry to
executing the print / echo statements). This worked fine for simple
print commands. However, a print command in a pipeline (e.g. print
'qwertyuiop;lkjhg' | cat -
) did not break, but core-dumped. Similarly for a print command in a
sub process (e.g.
( print 'qwertyuiop;lkjhg' )
). I believe the version of gdb that I got from version 3.3 of
freeBSD is 4.18 .
