Hello and many thanks to help.

Here demo to show the problem (i hope).

>> https://sites.google.com/site/fiensprototyping/dynlib_vs_windows.zip

There is a program : test.pas
It uses a external library soundtouch_2.dll.

There are 2 wrappers :
soundtouch_windows.pas (who uses windows unit) and 
soundtouch_dynlib.pas (who uses dynlib unit)

There are  also 4 binaries :

test_windows_fpc262.exe => OK, works (use soundtouch_windows.pas and compiled with fpc 262)

test_windows_fpc271.exe => NO, does NOT work (use soundtouch_windows.pas and compiled with fpc 271)

test_dynlib_fpc262.exe => NO, does NOT work (use soundtouch_dynlib.pas and compiled with fpc 262)

test_windows_fpc271.exe => NO, does NOT work (use soundtouch_windows.pas and compiled with fpc 271)

You may test the prog with soundtouch_windows.pas or soundtouch_dynlib.pas (uncomment the one you want in use section).

Many thanks.

Oops, forget about the 2.7.1. fpc binaries... (a 64 bit compiler was use in place of 32 bit)).

So, only take care about :

test_windows_fpc262.exe => OK, works (use soundtouch_windows.pas and compiled with fpc 262)

test_dynlib_fpc262.exe => NO, does NOT work (use soundtouch_dynlib.pas and compiled with fpc 262)

Many thanks.
