Hi,

I'm using LibRaw 0.18.8 in an Android application amongst other things to read thumbnails. I'm seeing a lot of crashes that I cannot reproduce. All I have to go on are slightly unhelpful backtraces:

backtrace:
  #00  pc 0000000000032e50  <...>.so (_ZN6LibRaw12unpack_thumbEv+1076)

and less often:

backtrace:
  #00  pc 0000000000048094  <...>.so (_ZN6LibRaw8identifyEv+1243)
  #01  pc 0000000000019a63  <...>.so (_ZN6LibRaw15open_datastreamEP26LibRaw_abstract_datastream+98)
  #02  pc 00000000000194c9  <...>.so (_ZN6LibRaw9open_fileEPKcx+128)

I have so far neither managed to get better backtraces nor to identify a picture to reproduce the error with. What I did notice though, is that almost all crashes seem to come from users of Chinese phones (Xiaomi, Oppo), while my overall user-base has only a very small share of these phones.

Not much to go on unfortunately. Could it that LibRaw chokes on Chinese metadata on Arm? Any idea how I can test that?

Any pointers appreciated. Thanks!
