Hi

Im using Centos 5 and Gambas 2.0.0 and when I call  a external function in a
C library this error occurs and Gambas crash with error #6....

EXTERN TEF_inicia(Resultado AS String, Funcao AS String, Valor AS String,
CuponFiscal AS String, DataFiscal AS String, Horario AS String, Operador AS
String, ParamAdic AS String) IN "libclisitef" EXEC
"IniciaFuncaoSiTefInterativoA"

DIM la AS String
TEF_inicia(la, "000000", "{200,00}", "{12345}", "20080618", "100000",
"{MARCOS}", "{}")
The variable "la" receive the return from function TEF_inicia.

This is the error that appears in console:
