Description Mark Wielaard 2020-06-24 13:27:44 UTC

+++ This bug was initially created as a clone of Bug #1850086 +++

There is a regression in valgrind 3.16.0 with some code compiled with -m32 -mfpmath=387 (32bit using 387 floating point).

Upstream already has a fix and has released 3.16.1 with it:
https://bugs.kde.org/show_bug.cgi?id=422715

The fix is fairly small and self contained.
But replicating the issue is not trivial.
