My use-case is downstream where I use FileCheck against stderr like this:
// a.cpp:
// RUN: DEBUG_OUR_RUNTIME=1 %t.out > %t.log 2>&1
// RUN: FileCheck %s < %t.log
//
// ...
// assert(Something);
Debug output is bigger than the threshold (although I only FileCheck a tiny bit of it) so without this change I don't see the failing assert when running llvm-lit. With the patch assert message is visible in the llvm-lit's output.
