error with re-entrant versions

[Masrur Doostdar]

Hi,

i get seg-fault errors using the re-entrant versions of some API-functions (cmd_line_parse_file_r and s3_decode_init_r) in latest version of sphinx 3.7. I need this re-entrant versions since i need 2 decoders in one programm each working with their own config-file.

To make my error reproducable i just edited some lines in the original main_livedecode.c code using the re-entrant versions of the functions:

--- main_livedecode.c.orig 2007-12-30 20:14:25.000000000 +0100
+++ main_livedecode.c 2007-12-30 20:16:01.000000000 +0100

• if (cmd_ln_parse_file_r(cmd_ln,S3_DECODE_ARG_DEFS, argv[1], TRUE)) {
  printf("Bad arguments file (%s).\n", argv[1]);
  return -1;
  }

  fe = fe_init_auto();

• if (s3_decode_init(&decoder)) {

• if (s3_decode_init_r(&decoder,cmd_ln)) {
  printf("Initialization failed.\n");
  return -1;
  }

With this I get a Seg-Fault:

besides my configuration (cfg-file, dictionary ...) is the same as postet here:

needless to mention, that i get no error with this cfg-file when using original main_livedecode.c file.

Regars and happy new year

Hm, I suppose you are incorrectly using the API here. We need a more clear version on how to work in list. The result of this function is not returned in the first argument but returned as a value. Moreover, first argument must be initialized to be a proper list, say must be NULL. So try this version instead:

• if (cmd_ln_parse_file(S3_DECODE_ARG_DEFS, argv[1], TRUE)) {
• cmd_ln_t * cmd_ln = NULL;
• if ((cmd_ln = cmd_ln_parse_file_r(cmd_ln,S3_DECODE_ARG_DEFS, argv[1], TRUE)) == NULL) {
