Binary compatibility of existing Motif binaries is not affected. Many parameters in the Motif Application Programming Interface (API) are of type XmString, which is an opaque type. Motif source code that uses char* where the Motif API expects an XmString parameter is always incorrect. Such incorrect Motif code is more likely to core dump when compiled in the Solaris 7 operating environment.
Workaround: Use an older version of Motif.
