The test also fails in 15D builds (on AMD64?) so you should be able to get a full stack trace. You can also compile with -g and -O but I'm not sure how readable it will make the code. If you can't get the argument values from the stack trace you might want to try good old printf.

As for the function arguments, they aren't shown in either the stack trace shown by the assertion or the debugger. The stack trace in the debugger looks like this: {noformat} ...

If so and the failure still occurs with this build, it'd be a lot easier to analyze. Currently, I'm just using plain ol' print statements.[AMD64] SIGABRT in 27.istream.fmat.arith ---------------------------------------- Key: STDCXX-828 URL: https://issues.apache.org/jira/browse/STDCXX-828 Project: C++ Standard Library Issue Type: Bug Components: Tests Affects Versions: 4.2.0 Environment: Sun C++ 5.9/Solaris/AMD64 Reporter: Martin Sebor Assignee: Eric Lemings Fix For: 4.2.1 Original Estimate: 4h Remaining Estimate: 4h When compiled with Intel C++ 10.0 on Linux/AMD64 or Sun C++ 5.9 on Solaris 10/AMD64, the test [27.istream.fmat.arith.cpp|http://svn.apache.org/repos/asf/stdcxx/trunk/tests/iostream/27.istream.fmat.arith.cpp] abends with SIGABRT. This was observed in 8{D,S}, 12{D,S} and 15D build types, not necessarily consistently on both platforms. The same test was also failing in 4.2.0 with Intel C++.
