I've run into this problem several times before... it seems to relate to
the sizes of the variables that are declared in lp5250d.c
For example, if your "output command" is more than 30 chars long, it will
cause problems because lp5250d only allocates 30 bytes to store it in.
When the system goes to actually print something, it does a popen() to
that output command, which causes it to assert or even segmentation fault.
"scs2ascii | lpr -Plinuxoptra"
123456789012345678901234567890
This is cutting it close, but doesnt appear to overflow. Is that the
string your using, or is it a bit more complex?
Also, the same problem exists with the hostname (20 chars), the
session name (20 chars -- tho 10 is the AS/400's max so this shouldnt be
too big of an issue), and the logfile's name (20 chars).
Perhaps these parameters should be allocated with malloc(), based on
the size of the arguments, so that we don't have this type of overflow?
I could write up a patch if you'd like...
Hope that helps...
