[Flac] problem with 24 bit odd size file (even in new version)
i had the problem is flac 1.1.2 so upgraded to 1.1.4 but now the problem is just
different. the wav file is from audacity, so i guess it is culprit
for setting that
format type 1 bit, but shouldn't this still work?
i found in 1.1.2 (before i found 1.1.3 had the odd size fix judging by
relnotes) that i could add a dummy byte to the end and this seems to
fix my issue, just not cleanly.
here is what i'm seeing with 1.1.4 under cygwin:

and here is stackdump i get (not sure at which point above):

Why worry, there should be laughter after the pain
There should be sunshine after rain
These things have always been the same
So why worry now

[Flac] problem with 24 bit odd size file (even in new version)
nothing should crash like that. if you can give some specifics about it I can take a look. but the wave file seems invalid. sample data is supposed to be padded to an even number of bytes.
