What steps will reproduce the problem?
1. Build with clang and -fsanitize=undefined
2. Use it
What is the expected output? What do you see instead?
The expected output is nothing.
Much output of the form: src/client/linux/minidump_writer/linux_dumper.cc:223:19: runtime error: store to misaligned address 0x7f71f11dd6f4 for type 'uintptr_t' (aka 'unsigned long'), which requires 8 byte alignment
There is problem in PageAllocator in src/common/memory.h
There is also a problem in src/client/linux/minidump_writer/directory_reader.h
What version of the product are you using? On what operating system?
Hmm, maybe r281 (I feel like it's about 6 months old, I will update and retest
tomorrow), on x86_64 Ubuntu 14.04. Compilation with clang 3.5.0 (trunk 211762)
Please provide any additional information below.
The patch is obviously less than ideal, but it makes the undefined behaviour go
away, so it should be a useful starting point.
