Descriptions

The REENT_CHECK macro (see newlib/libc/include/sys/reent.h) as used by REENT_CHECK_TM, REENT_CHECK_MISC, REENT_CHECK_MP and other newlib macros in versions prior to 3.3.0, does not check for memory allocation problems when the DEBUG flag is unset (as is the case in production firmware builds).

La macro REENT_CHECK (ver newlib / libc / include / sys / reent.h) como la utilizada por REENT_CHECK_TM, REENT_CHECK_MISC, REENT_CHECK_MP y otras macros newlib en versiones anteriores a la versión 3.3.0, no verifica si hay problemas de asignación de memoria cuando el indicador DEBUG está desactivado (como es el caso en las compilaciones de firmware de producción).
