Hy community,

I need your help/advice. I loaded crashdetect plugin to track down some errors in my script and somehow got into this problem:

pawn Code:

[13:05:08] Script[gamemodes/newegDB.amx]: In file 'I:\_eGaming\samp\_new_mysql-0.3d\__CORECTAT0.3c\pawno-3\include\float.inc' at line 108:
[13:05:08] Script[gamemodes/newegDB.amx]: Run time error 8: "Heap underflow"
[13:05:08] Error information:
[13:05:08]   Heap index (HEA) is 0x8B, heap bottom (HLW) is 0x3F20FC
[13:05:08] Call stack (most recent call first):
[13:05:08]   Stack corrupted!

The file float.inc is the standard file from samp(pawn) package.
the line 108 is:

pawn Code:

stock Float:operator-(Float:oper)
    return oper^Float:cellmin;                  /* IEEE values are sign/magnitude */

The problem appears on something very basic like:

pawn Code:

GetPlayerHealth(playerid, health);
SetPlayerHealth(playerid, health - 2.0);

if I modify the script into:

pawn Code:

GetPlayerHealth(playerid, health);
SetPlayerHealth(playerid, floatsub(health, 2.0));

The problem vanished.

Does anyone have any idea why this thing happens ?
Should I use Floatadd, Floatsub, Floatmul, Floatdiv functions instead of standard operators +,-,*,/ ?

My compile output is:

pawn Code:
