Bad drop of GCC DLLs?

[Dariusz Piatkowski]

ftp://ftp.netlabs.org/pub/gcc/ shows "gcc4core-1_2_1.wpi" dated 01/20/2012, I
pulled this and installed on my machine, however, prior to doing so noted that
GCC446.DLL was quite the different size then what I had already present:

CURRENT VERSION => 12-16-11 4:01a 131447 124 gcc446.dll
NEW VERSION => 12-16-11 4:01a 25115 0 gcc446.dll

...subsequently with the new version I found out that sound in VLC was at such a
low volume that it was almost un-heard...no matter what volume I adjusted it to,
etc, etc.

Reverting back to my old version brought back the 'proper' audio in VLC.

Hmm, I could bet that the only difference in these two DLLs is the
EXEPACK option.

And I have absolutely no idea what kind of bug in a C runtime could
cause the sound to be nearly quiet without to cause any other trouble.

How do I check the EXEPACK option? EXEHDR comes back with the following :

=== START ===
Library: gcc446
Description: GNU GCC Runtime Version 4.4.6

Module type: Dynamic link library
Per-process initialization
Global termination
NO internal fixups in executable image
Number of memory pages: 00000009 (9)
Initial CS:EIP: object 1 offset 00000000
Initial SS:ESP: object 0 offset 00000000
Automatic data object: 2

no. virtual virtual map map flags
address size index size
0001 00010000 00007c60 00000001 00000008 EXECUTABLE, READABLE, 32-bit
0002 00020000 00000a80 00000009 00000001 READABLE, WRITEABLE, 32-bit
=== STOP ===

Both DLLs show 92 entries and the EXEHDR listing is identical for both...but
that's also the extent of the tools I know of...lol...

Yeah, it was a very weird situation...no matter what I tried doing with the
UniMix mixer to increase the volume, which is already at about 90% as-is, made
no difference. All I can say is that reverting back to the 'old' DLL cured the
problem.

Either the DOS stub - by default LX executables contain a DOS stub,
although it makes not sense for one cent in case of DLLs - or different
compression options are used. The more appropriate way to compare
executables is to uncompress them and remove the DOS stub. This should
result in binary identical images.
