Abstract
VIOS (Doc Number=5763): High Impact / Highly Pervasive APAR IJ04075 IJ04075 - Applications calling __xmbrtowc() may core dump
Applications that call __xmbrtowc() may core dump on the latest Service Packs due to an illegal instruction in mbrtowc_wrap().
We have seen this primarily from applications that use the C++ Class wifstream, which calls __xmbrtowc(). These applications have included IBM Tivoli Monitoring and Microsoft SCOM for AIX.

IJ04511 iFix Note: Installation of these fixes requires a reboot.
The table above describes which active levels are affected and where to obtain fixes.
Prior to the APAR Fix being available, an Interim Fix (iFix) is available for each affected level.
The available iFixes may only apply to the latest Service Packs. If a custom iFix is required please contact IBM Support.
The iFixes can be downloaded from the same location using ftp, http, or https.
