Farid Zaripov resolved STDCXX-584. ---------------------------------- Resolution: Fixed > purify reports memory leak from __rw_vfmtwhat in 18.exception test > ------------------------------------------------------------------ > > Key: STDCXX-584 > URL: https://issues.apache.org/jira/browse/STDCXX-584 > Project: C++ Standard Library > Issue Type: Improvement > Components: Tests > Affects Versions: 4.2.0 > Reporter: Travis Vitek > Assignee: Travis Vitek > Priority: Trivial > Fix For: 4.2.1 > > Attachments: stdcxx-584.patch > > > The library uses a system of functions for platforms that don't support > exceptions. The __rw_throw function calls __rw_vfmtwhat() to get a string > describing the exception that has occured. Under some conditions the string > is allocated from the heap as an array of characters. Eventually __rw_throw > invokes a function via pointer (__rw_throw_proc) that is supposed to process > the exception (possibly by throwing a real exception object). Unfortunately > the test does not deallocate the string that was allocated by __rw_vfmtwhat(). > Purify: Searching for all memory leaks... > Memory leaked: 3072 bytes (25.6%); potentially leaked: 0 bytes (0%) > wLK: 3072 bytes leaked in 12 blocks > * This memory was allocated from: > malloc [rtlib.o] > operator new(unsigned) [libstd15d.so] > operator new [](unsigned) [libstd15d.so] > __rw::__rw_vfmtwhat(char*, unsigned, char const*, char*) > [exception.cpp:479] > __rw::__rw_throw(int, ...)
