if (IMCC_INFO(interp)->error_code) {
char * const error_str = Parrot_str_to_cstring(interp,
IMCC_INFO(interp)->error_message);
IMCC_INFO(interp)->error_code=IMCC_FATAL_EXCEPTION;
fprintf(stderr, "error:imcc:%s", error_str);
IMCC_print_inc(interp);
Parrot_str_free_cstring(error_str);
Parrot_x_exit(interp, IMCC_FATAL_EXCEPTION);
}
imc_cleanup(interp, yyscanner);
In the error branch main.c is not calling imc_cleanup so valgrind gives
the following output:
==4322== 222 (208 direct, 14 indirect) bytes in 1 blocks are definitely
lost in loss record 238 of 508
