DevIL segfault, issues with png's, bmp's - c++

Question

I am on mingw (gcc version 4.5.2).
I get a segfault when opening certain files, including PNGs and BMPs. It was working fine on a 128x128 PNG but when I started testing with larger files I started getting a segfault. There are no issues with the TGA format, though. I know the library works for the most part, but not knowing whether it will decide to crash and burn like this is not good.
gdb does not give me any hints about what's going on. I am able to compile DevIL from source, and I compiled a debug dll (--enable-debug for configure script) but it doesn't seem to support png (seems like I need to get a png12 library) but it doesn't get me very far.
I am trying to open a ~2MB BMP I made in GIMP. I run it through GDB and it sometimes will segfault but other times it warns of some stuff happening on the heap (lots of stuff i've never seen before). Here's a gdb run dump. All of the lines beginning with %%% are the output that is specific to my program, the rest comes from gdb.
$ gdb ./entropy_unittest_disp.exe loadpngdisplay

the test ilWritePng is actually just having it write a .tga image file. That test works fine with the release dll (md5 = 59E291838AE2C88F5F71108E4845A84B) but this debug build I compiled has more issues.
I was so happy when I skimmed the doc and got DevIL up and running in like 10 minutes. I figured it was going to save me so much work...
This is making me start to wonder if I should just implement my own image file format (I would use PPM binary and shove it through a compression stream).
edit: source code:
#include "Texture.h" // for Pixel struct
#include "Script.h" // for lua (quick and dirty shell access)
TEST_FIXTURE(ILSystem, ilWritePng) { // ILSystem calls ilInit(), ilShutDown() in ctor, dtor respectively
ILuint image;
ilGenImages(1,&image);
CHECK(ilGetError()==0);
ilBindImage(image);
Pixel pixels[128*128];
for (int i=0;i<128;++i) { for (int j=0;j<128;++j) {
Pixel &p = pixels[i*128+j];
p.b = 0; p.g = i; p.r = j; p.a = 0xff;
}} // neat and simple test image, a greenish purplish gradient type thing.
CHECK(ilTexImage(128,128,1,4,IL_BGRA, IL_UNSIGNED_BYTE,pixels));
CHECK(ilGetError()==0);
{
LuaSystem l;
l.dostring("os.execute(\"rm output_il.tga\")"); // delete that file
}
ilSaveImage("output_il.tga");
PRINT_INT(ilGetError());
}
#ifdef LOAD_DISPLAY
