<pre>`try-catch` block in a code build with clang, and linked using gold (binutils
2.21.1), doesn't catches exceptions:
Tested on 3.8 LLVM, and trunk:
LLVM git c1b22faefa9f470405e4d3bf3150eb694a0c439a
Clang git 612eea8a21b02346124f671b4fafd8bf064218ab
```
$ cat a.cpp
int main() {
try {
throw 42;
} catch (...) {
}
return 0;
}
$ clang++ -B<path to binutils 2.21.1>/bin/gold -L<path to glibc 2.20>/lib a.cpp
$ ./a.out
terminate called after throwing an instance of 'int'
[Exit 134 (ABRT)]
```
Bisected to the following change in LLVM: git
20db4731726eded30dd7bcd6702a7e7498bf7b29 (corresponding Clang git
db7ff082d2dbfb035d6ef21a107727ae61bf1e46)
A quick search suggests that there was a bug in gold:
<a href="https://sourceware.org/ml/binutils/2011-06/msg00376.html">https://sourceware.org/ml/binutils/2011-06/msg00376.html</a>
Not sure if this should be fixed in LLVM, but worth mentioning somewhere in
documentation.</pre>
