Please upgrade to at least 1.0.6 (latest stable), there are  
several segmentation faults fixed in it since 1.0.4.

If it doesn’t help, please upgrade to 1.1.3 (latest devel), there  
are fixes for several segmentation faults which weren’t yet merged  
into stable branch.

If it doesn’t help either, please follow procedure described here:

Notably, please provide nginx -V output, full config and stack  
trace for segfaults you see.
