#89 Curious crash

[Aupeix Alain]

Hi,
here is a problem I have using more than one time an image object:

public cHex_white:="", cVal_white:="", oObj_white:=""

// --------- white.png ----------------
cHex_white := ;
"89 50 4E 47 0D 0A 1A 0A 00 00 00 0D 49 48 44 52 " + ;
"00 00 00 18 00 00 00 18 08 06 00 00 00 E0 77 3D " + ;
"F8 00 00 00 01 73 52 47 42 00 AE CE 1C E9 00 00 " + ;
"00 06 62 4B 47 44 00 00 00 00 00 00 F9 43 BB 7F " + ;
"00 00 00 09 70 48 59 73 00 00 0B 13 00 00 0B 13 " + ;
"01 00 9A 9C 18 00 00 00 07 74 49 4D 45 07 E3 03 " + ;
"15 10 20 18 E6 AD 01 75 00 00 00 19 74 45 58 74 " + ;
"43 6F 6D 6D 65 6E 74 00 43 72 65 61 74 65 64 20 " + ;
"77 69 74 68 20 47 49 4D 50 57 81 0E 17 00 00 00 " + ;
"28 49 44 41 54 48 C7 63 BC 73 E7 CE 7F 06 1A 02 " + ;
"26 06 1A 83 51 0B 46 2D 18 B5 60 D4 82 51 0B 46 " + ;
"2D 18 B5 60 D4 02 EA 00 00 5C EB 03 C3 EE 39 63 " + ;
"E5 00 00 00 00 49 45 4E 44 AE 42 60 82 "

cVal_white := hwg_cHex2Bin(cHex_white)

oObj_white := HBitmap():AddString( "white" , cVal_white )

@ hbloc+27,vbloc+27 OWNERBUTTON oAa OF oGrille SIZE 24, 24 ;
BITMAP oobj_white FLAT ID 1101
hbloc+=27
@ hbloc+27,vbloc+27 OWNERBUTTON oAb OF oGrille SIZE 24, 24 ;
BITMAP oobj_white FLAT ID 1102
hbloc+=27
@ hbloc+27,vbloc+27 OWNERBUTTON oAc OF oGrille SIZE 24, 24;
BITMAP cImageDir+"white.png" FLAT ID 1103

If I use 'cImageDir+"white.png"' more than one time (about 200) in the same function => it works
If I replace it with 'oobj_white' only one time, it works
If I replace it more than one time, it crashes :

Where do I fail ?

Hello Alain,
based on your sample code in the post to ticket i
created a complete sample program.
It does not crash and the no GTK message appear.
More comments in test program.

Hello Alain,
i created a new directory
test/tickets
for handling test programs for ticket support.
Here you find the sample
Sticket89.prg
with hbp and image files in "image".

Hi Wilfried,

No flat, no OF param, but crashes if more than one button is using the same image object.

Hello Alain,
with commit r3829 i have done
some more modifications,
but no crash appeared.

Can you modify the sample
to provocate the crash ?
