Bug 416779

Tested with VALGRIND_3_15_0-193-gfe6805efc

STEPS TO REPRODUCE
1. build wine, with https://github.com/mstorsjo/llvm-mingw/ and enable pdb symbols
2. cd ./dlls/crypt32/tests
3. make cert.ok

Result:
../../../tools/runtest -q -P wine -T ../../.. -M crypt32.dll -p crypt32_test.exe cert && touch cert.ok

valgrind: m_debuginfo/debuginfo.c:454 (discard_or_archive_DebugInfo): Assertion '!di->have_dinfo || is_DebugInfo_active(di)' failed.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

make[1]: *** [Makefile:234: cert.ok] Error 1

Expected result:
Assertion doesn't fail

Note that this occurs for many, but not all, tests. Out of the first 176 tests (I had to stop for unrelated reasons), 41 tests showed this failure.
