2017-11-28Fix PDF fuzzers memory limitNicolas Pena
This CL reduces the memory limit in pdf_codec_jbig2_fuzzer. Note that MSAN requires the limit to be lower than the actual bot usage limit. In the testcase, we get OOM just after CFX_DIBitmap::Create. It also increases the limit in xfa_codec_fuzzer.h Bug: 784155 Change-Id: I6fc8d9533ca7dc2b19bf84b9eac23284e05b1e6d Reviewed-on: https://pdfium-review.googlesource.com/19571 Commit-Queue: Nicolás Peña Moreno <npm@chromium.org> Reviewed-by: dsinclair <dsinclair@chromium.org>
