Error description
Customer is running on OS/390 R10 and changed the ARCHLVL in
sys1.parmlib to 2 indicating that they wanted 64 bit addressing
opposed to 31 bit addressing.  The HTTP plugin abends with an
abend0c4 in _dofmto when changing to 64 bit mode.  In 32 bit
mode it does not abend but the trace entries are formatted
incorrectly in the HTTP Plugin code.
   You can determine if you are in 64bit mode by finding the
64 bit PSW. NOTE: psw starts with BIT zero.
  24-BIT addressing: Bits 31 and 32 are zero
  31-BIT addressing: Bit 31 is zero and BIT 32 is one.
  64-BIT addressing: Bits 31 and 32 are one.

****************************************************************
When z/OS is configured for 64-bit mode, the Http Plugin will
abend 0C4 while executing an fprintf within the tracing code.
When z/OS is configured for 31-bit mode, the Http Plugin will
not abend; however, trace point data may contain formatting
errors.
Problem conclusion
The problem occurs when the tracing code attempts to print the
pthread id.  The pthread id is 8 bytes in length on z/OS and
the tracing code was originally written to handle a 4-byte
pthread id.  The tracing code was changed to correctly print an
8-byte pthread id.
