allocating 0 bytes in xmi

[Johannes Zellner]

Hi,

in lib/libxmi/xmi/gc.c:42 I'd suggest a

    new_gc->numInBlendStageList = nblendstages;
+   if (nblendstages > 0) {
        new_gc->blendstages = (miBlendStage *)malloc(nblendstages * 
sizeof(miBlendStage));
        for (i = 0; i < nblendstages; i++)
          new_gc->blendstages[i] = blendstages[i];
+   } else {
+       new_gc->blendstages = (miBlendStage *)0;
+   }

for preventing the allocation of 0 bytes. How is malloc(0) expected
to behave ? -- my 'malloc man page' does not tell anything about this,
but at least efence reports:

    ElectricFence Aborting: Allocating 0 bytes, probably a bug.
    Illegal instruction (core dumped)
