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.
