Bug #: 31507
Summary: midiInOpen x64 crash due to callback address 32-bit
truncation
Product: Wine
Version: unspecified
Platform: x86-64
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: winmm&mci
AssignedTo: wine-bugs at winehq.org
ReportedBy: georgewi at oss3d.com
Classification: Unclassified
midiInOpen seems to crash at calling the address, which looks like the lower
32-bit of the callback function address passed to it as a parameter.
I believe, the callback address is somewhere truncated from 64-bit to 32-bit in
the internal logic.
The affected software is this (64-bit standalone executable):

I couldn't find the exact reason for this problem within wine sources.
