Could you provide a little more background?
1) pyramids were built internal or external?
2) which resampling method?
3) is the tif paletted?
4) what OS and version of GDAL are you using?
thanks

1) External pyramids seem ok. Internal cause a crash, and the resulting tiff is reddish with the missing tile
2) average
3) GDT_Byte - Eight bit unsigned integer Image Structure Metadata:
COMPRESSION=JPEG
INTERLEAVE=PIXEL
4) tested with Debian Lenny, both on 32 and 64 bit, plus 64 bit Fedora; GDAL 1.5.2-3

I was able to reproduce. It seems to be size dependent. Pyramids built ok on an 80x80 image but crashed on 8000x8000.
When it crashes I get
--> tif_jpeg.c:691: JPEGPreDecode: Assertion @sp->cinfo.comm.is_decompressor' failed.
So it is a GDAL problem. Will have to look through their tickets to see if this is a known problem.

Strange however: apparently GDAL does not crash on the same task when called from the command line

I can reproduce the crash from the command line as well.
looks like it is a know problem, that has been closed but not really fixed

May have to consider not allowing pyramids to be build for JPEG compressed tifs.

-internal pyramid building with compress rasters, specifically JPEG compress is no longer enabled.
This can be re evaluated after libtiff 4+ comes out.

Ticket #2033 was closed because the fix for it went to libtiff 4.0 branch, but libtiff < 4.0 has still the issue.
So I'm attaching a patch that enables to build safely overviews on Jpeg files or Jpeg-in-TIFF file by checking that GDAL uses libtiff >= 4.0. The "official" trick to do that is searching 'BIGTIFF' in the creation options of the GTiff driver.
