[gcc 4.0.1/Mac OS X] SIGABRT throwing an exception
--------------------------------------------------

                 Key: STDCXX-600
                 URL: https://issues.apache.org/jira/browse/STDCXX-600
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 18. Language Support
    Affects Versions: trunk
         Environment: gcc 4.0.1 on Darwin Kernel Version 8.10.1
            Reporter: Martin Sebor
            Priority: Critical


Throwing an exception from the library causes a SIGABRT. Example programs that demonstrate
library exceptions abort, as does the program below:

$ cat t.cpp && make t && gdb -q t
#include <string>

int main ()
{
    try {
        std::string s;
        s.replace (1, 1, "x");
    }
    catch (...) {
    }
}

-I/Users/sebor/stdcxx/examples/include  -pedantic -nostdinc++ -g  -W -Wall -Wcast-qual -Winline
