Note, though, that the PR has not yet been merged, and I'm actually surprised that it fixes the issue for you, since your ODBC trace hints at missing trailing NUL bytes, for what the patch doesn't cater to. Particularly, there is likely an assertion failure with debug builds. ------------------------------------------------------------------------ [2021-02-23 08:20:28] horvath dot szabolcs at t-systems dot hu Thank for your quick response! It seems the bug has been fixed. Nice job. Anyone coming from RHEL systems: I opened a support ticket (Case 02876261) asking for a backport to their SCL tree. ------------------------------------------------------------------------ [2021-02-22 14:24:02] cmb@php.net Could you please *test* the patch? Note though, that PHP 7.3 is no longer actively supported, so the patch targets PHP 7.4. It may still work with PHP 7.3, though. ------------------------------------------------------------------------ [2021-02-22 14:21:49] cmb@php.net The following pull request has been associated: Patch Name: Fix #80783: PDO ODBC truncates BLOB records at every 256th byte On GitHub: https://github.com/php/php-src/pull/6716 Patch: https://github.com/php/php-src/pull/6716.patch ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
