Hey there, we are using UV in a C++ project tested with GoogleTest and want to use valgrind.
If we run each test individually - via the gtest_filter using valgrind, all tests run just fine and leak no memory. But if we want to run the whole suite we get various valgrind complains, although the tests finish successfully. Without using MAKE_VALGRIND_HAPPY() at the end of the test, the complains look like this: ==14376== Invalid write of size 8 > > ==14376== at 0x42D299: uv__stream_init (stream.c:113) > > ==14376== by

issues occur on both OSX 10.9 and Arch64 with both the gcc version 4.8.2 and clang version 3.4 build chain. We are using UV 2014.01.30, Version 0.11.19 and GoogleTest 1.7.0. There are some comments in the test headers regarding valgrind - if we got that right valgrind is used as usual with the command line options --leak-check=full --quiet. We also tried debugging the invalid read, but couldn't find out more. Do you have any idea where this errors could come from? We assume its somewhere along the test shutdown, but how can we fix that? Thank you for your help, our heads are melting here! Best regards and thanks for any clues, Tommy -- You received this message because you are subscribed to the Google Groups "libuv" group.
