As a result, iconv (the function) returns E2BIG instead of EILSEQ. The iconv program does not see the original EILSEQ failure, does not recognize the invalid input, and may incorrectly exit successfully. To address this, a new __flags bit is used to indicate a sticky input error state. All __GCONV_ILLEGAL_INPUT results are replaced with a function call that sets this new __GCONV_ENCOUNTERED_ILLEGAL_INPUT and returns __GCONV_ILLEGAL_INPUT. The iconv program checks for __GCONV_ENCOUNTERED_ILLEGAL_INPUT and overrides the exit status. The converter changes introducing __gconv_mark_illegal_input are mostly mechanical, except for the res variable initialization in iconvdata/iso-2022-jp.c: this error gets overwritten with __GCONV_OK and other results in the following code. If res == __GCONV_ILLEGAL_INPUT afterwards, STANDARD_TO_LOOP_ERR_HANDLER below will handle it. The __gconv_mark_illegal_input changes do not alter the errno value set by the iconv function. This is simpler to implement than reviewing each __GCONV_FULL_OUTPUT result and adjust it not to override a previous __GCONV_ILLEGAL_INPUT result. Doing it that way would also change some E2BIG errors in to EILSEQ errors, so it had to be done conditionally (under a flag set by the iconv program only), to avoid confusing buffer management in other applications.
