SQL Loader bug

Question

2 day ago I meet with problem to load text file to Oracle DB with
SQL statment in control file. It's my control file:
LOAD DATA
INFILE '/tmp/123/22-12.txt'
REPLACE
INTO TABLE VL_LOG
(date_time SYSDATE,
SOURCE POSITION(02:16)
"TRUNC(SUBSTR(:SOURCE,1,3))*16777216+TRUNC(SUBSTR(:SOURCE,INSTR(:
SOURCE,'.')+1,3))*65536+TRUNC(SUBSTR(:SOURCE,INSTR(:SOURCE,'.',1,
2)+1,3))*256+RTRIM(SUBSTR(:SOURCE,INSTR(:SOURCE,'.',-1)+1))",
DESTINATION POSITION(19:33)
"TRUNC(SUBSTR(:DESTINATION,1,3))*16777216+TRUNC(SUBSTR(:DESTINATI
ON,INSTR(:DESTINATION,'.')+1,3))*65536+TRUNC(SUBSTR(:DESTINATION,
INSTR(:DESTINATION,'.',1,2)+1,3))*256+SUBSTR(:DESTINATION,INSTR(:
DESTINATION,'.',-1)+1)",
bytes POSITION(54:72) INTEGER EXTERNAL)
When I run SQL Loader with this control file my Linux 5.2
(kernel 2.0.36) say:
Segmentation fault(core dumped).
Later I test this and now may say, that error is only when length
of SQL statment more than 201 bytes(symbols). I think, that input
buffer for this statment to small and loader fault when attempt
to translate incomlete string. I know, that Loader may translate
statments only shorter 258 symbols, and when statment string
greater 258 show error, but not core dumped!

255 is default length. If you need more - specify it exactly as char(2000). You searched wrong forums. I'd suggest you to read manuals instead:
