I'm using PSAPI.DLL functions like EnumProcesses(). It works
fine as long as I use the import library. But when I use dynamic
binding via GetProcAddress() it crashes in trying to call my
func-pointer. I'm using gcc + MingW. A small snippet:

static BOOL (WINAPI *_EnumProcesses) (ULONG*, ULONG, ULONG*);

ULONG processIds [256], numProcesses;

if (!(*_EnumProcesses) (processIds, sizeof(processIds), &numProcesses))
return (0);

/* Crashes above */

Results of LoadLibrary/GetProcAddress seems fine to me:

LoadExtendedFuncs(): ntdll.dll, RtlInitUnicodeString -> 77F941F8
LoadExtendedFuncs(): ntdll.dll, RtlNtStatusToDosError -> 77F939A6
LoadExtendedFuncs(): psapi.dll, EnumProcesses -> 76BE2FCE
LoadExtendedFuncs(): psapi.dll, EnumProcessModules -> 76BE1913
LoadExtendedFuncs(): psapi.dll, GetModuleFileNameExA -> 76BE1A45

My other func-pointer seems okay. Here's the register dump from DrMingW:

sof.exe caused an Access Violation at location 76be2fce Reading from location 76be2fce.

Registers:
eax=76be2fce ebx=003d3cb8 ecx=00000000 edx=00000000 esi=00000020 edi=0022fee8

> if (!(*_EnumProcesses) (processIds, sizeof(processIds), &numProcesses))

return (0);

Any ideas?
