New issue 343 by earth...@google.com: asan_symbolize.py sometimes omits
newlines in stack traces
https://code.google.com/p/address-sanitizer/issues/detail?id=343
Ex:
==13== WARNING: MemorySanitizer: use-of-uninitialized-value
#0 0x7ff96110a852
(/mnt/ssd/chromium/src/out_goma_msan_chained/Release/content_shell+0x4441852)
#1 0x7ff961109b9e
(/mnt/ssd/chromium/src/out_goma_msan_chained/Release/content_shell+0x4440b9e)
becomes (note the lack of :
==13== WARNING: MemorySanitizer: use-of-uninitialized-value
#0 0x7ff96110a852 in FindAllocationMemento
v8/src/heap/heap-inl.h:508:27 #1 0x7ff96110a852 in
_ZN2v88internal8JSObject20UpdateAllocationSiteENS0_6HandleIS1_EENS0_12ElementsKindE
v8/src/objects.cc:12663:0

I don't know whether this happens only to inlined functions (seems likely).
I think this regressed a few months ago.
