PH52786: "NOT ENOUGH STORAGE WAS AVAILABLE FOR THE WSA" WITH STRINGSTREAM

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Usage of the C++ stringstream class appears to be leaking memory
  after repeated usage of the operator >>.  When memory is no
  longer available, the following runtime error message is output:
  
  
  CEE3536S Not enough storage was available for the WSA.
           From entry point __cxa_throw at compile unit offset
           +00000000267BA462 at entry offset +00000000000000AA at
           address 00000000267BA462.
  
  
  No user C++ exception usage is present, but the crash occurs in
  the __cxa_throw function after an internal call to new() via the
  system locale functions:

  The issue will occur sooner if the 'ulimit -M' memory above bar
  limit is set low, or if there are a large number of calls to
  stringstream's operator >>.
  

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: IBM Open XL C/C++ 1.1 users using code that  *
  *                 involves locales                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: Applications using locales may run out  *
  *                      of memory                               *
  ****************************************************************
  * RECOMMENDATION: Install the PTF.                             *
  ****************************************************************
  Code that involves locales can leak memory. As a result, over
  time memory will be consumed. When the memory limit is reached
  the program will be killed. This PTF fixes the memory leak.
  

Problem conclusion

• IBM is releasing a cumulative update to IBM Open XL C/C++ 1.1
