Error description

  • This APAR has been opened to address a fault in the compiler
used to build DB2 V9.1.
The compiler fault results in incorrect Itanium speculative load
recovery code being generated.

When the problem is encountered DB2 will crash and generate a
trap file clearly indicating a NaT consumption fault:

Signal #4 (SIGILL): si_addr is 0xC000000013014D50, si_code is
0x00000009 (ILL_REGNAT:Register NaT Consumption)

Later releases of DB2 are not affected by this problem as a
newer compiler is used.
