dump_syms fails with segmentation fault when trying to create symbol file for Android .so file

What steps will reproduce the problem?
1. Build an Android (armeabi) shared library with the Android NDK (r10d)
2. Build latest breakpad on 64bit linux with any compiler (tried gcc-4.6, 
gcc-4.8, gcc-4.9 and clang-3.4) 
3. Try to execute dump_syms to get symbol file for the built Android shared 
library.

What is the expected output? What do you see instead?
Expect normal output of dump_syms with some warnings.
What I get:
 - Loads of warnings "failed to demangle _ZNSt3__xxxxxxxxxxxxxxxxxx with error -2"
 - Eventually segmentation fault

What version of the product are you using? On what operating system?
Latest (fresh) checkout of google-breakpad.
