• Key: STDCXX-600
• Type: Bug
• Status: Open
• Priority: Minor

• Component/s: 18. Language Support
• Affects Version/s: 4.2.0, 4.2.1
• Fix Version/s: 4.2.2

Description

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 (...) {
}
}
