Description Keith Slavin 2003-03-13 21:19:20 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830

Description of problem:
I compiled a very large (generated) C file with very little except
a very large statically initialized array of structs. Mostly it gives the
message below, but sometimes it compiles.

gcc temp.c -c -o temp.o
../c_intermediates/cda_cache.c: In function `AF_CDA_Cache':
../c_intermediates/cda_cache.c:506993: internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.


I can email the preprocessed and compressed .c file (4,596,187 bytes AFTER
compression) by request.

Version-Release number of selected component (if applicable):
gcc 3.2

How reproducible:
Sometimes

Steps to Reproduce:
1. Get temp.c.gz file from me
2. unzip temp.c,gz
3. gcc temp.c -c -o temp.o


Actual Results:  ../c_intermediates/cda_cache.c: In function `AF_CDA_Cache':
../c_intermediates/cda_cache.c:506993: internal error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.


Expected Results:  It should have produced a temp.o file with no internal error.


Additional info:

Running 1GHz athalon system, 1GByte RAM, Red Hat Linux 8.0
