FWH64 : ERROR SE SALE DEL SISTEMA

[Antonio Linares]

Carlos,

Investigando en el error de xHarbour 64, no es tanto por el uso de hb_gcAll() sino por estas dos líneas en tu función CheckConect()

IsQry:= oServer:Query("Select 1")
IsQry:End()

Si comentas esas dos líneas, hb_gcAll() funciona bien

Estamos más cerca de resolverlo...

[Enrico Maria Giordano]

I need a minimal PRG sample to reproduce the problem here, sorry. Carlos, can you provide it?

[CARLOS ATUNCAR]

Antonio, lo cambie de esta forma

if oServer:ping()
IsQry:= oServer:QueryResult("Select 1")
Else
lConn := .F.
Endif

y descomente HB_GCALL( .F. ) // limpiamos la memoria

y si trabaja sin problema, pero con las lib que enviastes no he probado con las lib de la descarga

[CARLOS ATUNCAR]

Antonio, he creado este ejemplo y lo he compilado con buildx64.bat y si funciona lo anterior

[Antonio Linares]

Estimado Carlos,

Es que el método End() al llamar o oWait:End() llama a hb_gcAll()

Enrico ya ha localizado el bug en xHarbour y esta trabajando para arreglarlo

[Enrico Maria Giordano]

What about removing all the calls to hb_gcall() from your program? Do you see any visible negative effect?

[Antonio Linares]

Dear Enrico,

We need to fix the xHarbour hb_gcAll() bug

[Enrico Maria Giordano]

I'm not sure it is a bug in xHarbour. However, I absolutely cannot fix it. I wrote to Ron in the xHarbour newsgroup. He's the only one that could understand the problem.

[Antonio Linares]

Dear Enrico,

> I wrote to Ron in the xHarbour newsgroup

Could you please provide the url to the posted msg ? many thanks

[Enrico Maria Giordano]

There is no url for usenet. You have to use a news client (I'm using Thunderbird) and subscribe to a news server (I'm using eternal-september.org).

[Antonio Linares]

Is it in google groups ?

thank you

[Enrico Maria Giordano]

Google Groups is not updated with new usenet messages since February (Google decision).

[CARLOS ATUNCAR]

Saludos Antonio, algún avance ?
