APAR status
Closed as program error.
Error description
When enabling function inlining via -Q or -qinline, the inline version of the getline(basic_istream&, basic_string&) function from the <string> standard header may be inlined, causing invalid exception handling for any subsequent exceptions that are thrown. template<class _E, class _Tr, class _A> inline basic_istream<_E, _Tr>& getline(basic_istream<_E, _Tr>& _I, basic_string<_E, _Tr, _A>& _X) {return (getline(_I, _X, _I.widen('\n'))); } The stack trace may look like: IOT/Abort trap in raise.raise at 0xd02c2904 0xd02c2904 (raise+0x40) 80410014 lwz r2,0x14(r1) raise.raise(??) at 0xd02c2904 abort() at 0xd0326778 std::myabort()() at 0xd091330c std::terminate()() at 0xd091286c exceptio.std::terminate().terminate()() at 0xd091278c __DoThrowV6() at 0xd09151e8 main(0x1, 0x2ff21994) at 0x10006cf0
Local fix
Use the non-inline version of the function, by specifying the getline() delim parameter, i.e. getline(inf, line, '\n'); template<class _E, class _Tr, class _A> basic_istream<_E, _Tr>& getline(basic_istream<_E, _Tr>& _I, basic_string<_E, _Tr, _A>& _X, const _E _D);
Problem summary
PROBLEM DESCRIPTION: Exception catch handler is missed after inlining is performed. USERS AFFECTED: The problem may be exposed when functions called from a try block are inlined after a block inside the try block with a return statement. There are cases where the try block could be missed.
Problem conclusion
The problem has been resolved.
