Отладка при помощи gdb

[kosh1984]

Всем приятного выходного.
Пытаюсь отладить Wine при помощи gdb. Собрал его с CFLSGS=-g на Ubuntu 8.04.
При попытке отладить, gdb выдает:

gdb wine setup.exe
GNU gdb 6.8-debian

"/home/koshev/distr/1csetup/Platform/setup.exe" is not a core dump: File format is ambiguous

На fedora 8 при той же схеме отладка просто прекрасна.
В чем может быть косяк?
