[Done] PureBasic 6.40 alpha 1 - memory leak
Posted: Fri Jan 23, 2026 4:27 pm
When calling a WinAPI function, with a string concatenation, which causes a memory leak.Probably a memory leak due to the pointer s1is not freed.
Code: Select all
Procedure Test(Num)
For i=0 To 10000000
CreateSemaphore_(#Null, 0, 1, "Semaphore"+Num)
Next
EndProcedure
Test(0)
MessageRequester("","")Code: Select all
// Procedure Test(Num)
static integer f_test(integer v_num) {
integer r=0;
void *s1;
integer v_i=0;
// For i=0 To 10000000
v_i=0;
while(1) {
if (!(((integer)10000000LL>=v_i))) { break; }
// CreateSemaphore_(#Null, 0, 1, "Semaphore"+Num)
void *r0=PB_Str(v_num);
s1=SYS_ConcatString(r0,&_S2[4]);
integer r1=f_createsemaphore_(0LL,0LL,1LL,s1);
// Next
next1:
v_i+=1;
}
il_next2:;
// EndProcedure
r=0;
end:
return r;
}
