Can't see nothing wrong with this...
void fl_set_object_label(FL_OBJECT * ob, const char *label) {
...
if (!label)
label = "";
...
ob->label = fl_realloc(ob->label, strlen(label) + 1);
strcpy(ob->label, label);
}
However, in your backtrace can I draw your attention to "oldsize" in item 6
#6 0x40414114 in chunk_realloc (ar_ptr=0x404b4680, oldp=0x8418c04,
oldsize=4294967292, nb=16) at malloc.c:3390
what does
std::cerr << static_cast<unsigned int>(-1) << std::endl;
give on your machine?
