[Bug 464088] [NEW] Buffer overflow in Idb__HDR_GetHeader() (with fix)

[Benjamin Herrenschmidt]

Public bug reported:

This bug breaks some apps I need to use that rely on libMrm.so.3, they segfault
due to a buffer overflow on the stack

The bug is trivial. It's using an XtNumber (aka ARRAY_SIZE) instead of strlen() to get the size
of a string declared as a char * ... FAIL :-)

The attached patch fixes it. Please apply. It's fixed in OpenMotif 2.3.x but Ubuntu is still at 2.2.x
and the app I'm using requires 2.2.x anyways.

** Affects: openmotif (Ubuntu)
