Is it possible to change the value of ASan's allocator_may_return_null at runtime or somehow disable this check temporarily? If I install an LLVM bad_alloc_error_handler, ASan's allocator wrapper detects this first and terminates the process instead of returning 0, preventing the custom handler from being called.<br class=""></blockquote><div class=""><br class=""></div>Is this question related to "r312582 - Revert "[Decompression] Fail gracefully when out of memory”"? </div></div></div></div></blockquote><div><br class=""></div><div>It is! Though even if we don't need it, I’d still be interested to know whether this is possible. If the answer is no, I wonder how useful error handler is (which isn't currently used, at least not upstream). </div><br class=""><blockquote type="cite" class=""><div class=""><div dir="ltr" class=""><div class="gmail_extra"><div class="gmail_quote"><div class=""> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
