So it seems solved now. I will try if mozilla now builds w/o
lto-partition=none passed to C compiler.

It also appears with lto-partition=none with profile feedback, so it is not
WHOPR only bug.

In the Firefox case sqlite3.o gets compiled correctly,
it is libmozsqlite3.so that segfaults when compiled with -flto
and -fprofile-use :
gcc -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -W -pedantic
-Wno-long-long -march=native -fpermissive -fno-strict-aliasing -pthread -pipe
-DNDEBUG -DTRIMMED -flto=4 -fwhole-program -fprofile-use -fprofile-correction
-Wcoverage-mismatch -freorder-blocks-and-partition -O3 -fPIC -shared
-Wl,-z,defs -Wl,-h,libmozsqlite3.so -o libmozsqlite3.so sqlite3.o
-lpthread -Wl,-O1,--hash-style=gnu,--as-needed,--no-keep-memory -fprofile-use
-Wl,-rpath-link,/var/tmp/mozilla-central/moz-build-dir/dist/bin
-Wl,-rpath-link,/usr/lib -ldl
This version runs fine (no -flto):
gcc -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -W -pedantic
-Wno-long-long -march=native -fpermissive -fno-strict-aliasing -pthread -pipe
-DNDEBUG -DTRIMMED -Wcoverage-mismatch -freorder-blocks-and-partition
-fwhole-program -fprofile-use -O3 -fPIC -shared -Wl,-z,defs
-Wl,-h,libmozsqlite3.so -o libmozsqlite3.so sqlite3.o -lpthread
-Wl,-O1,--hash-style=gnu,--as-needed,--no-keep-memory
-Wl,-rpath-link,/var/tmp/mozilla-central/moz-build-dir/dist/bin
-Wl,-rpath-link,/usr/lib -ldl
And this one gives an internal compiler error (only -flto , no -fprofile-use):
gcc -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -W -pedantic
-Wno-long-long -march=native -fpermissive -fno-strict-aliasing -pthread -pipe
-DNDEBUG -DTRIMMED -Wcoverage-mismatch -freorder-blocks-and-partition -flto -O3
-fPIC -shared -Wl,-z,defs -Wl,-h,libmozsqlite3.so -o libmozsqlite3.so sqlite3.o
-lpthread -Wl,-O1,--hash-style=gnu,--as-needed,--no-keep-memory
-Wl,-rpath-link,/var/tmp/mozilla-central/moz-build-dir/dist/bin
-Wl,-rpath-link,/usr/lib -ldl
lto1: internal compiler error: Floating point exception
Please submit a full bug report,
with preprocessed source if appropriate.

(All these commands should be run from:
./mozilla-central/moz-build-dir/db/sqlite3/src
One can copy the resulting libmozsqlite3.so directly into
/usr/lib/firefox-4.0b13pre and try to start Firefox, to check
if it's OK or not)

This should be easy to fix. Having backtrace would save me from some burden
trying to reproduce it ;)

It is in mainline, I should backport it to 4.6.1. Will try to do it today or

OK, division by 0 should be fixed both on mainline and 4.6 branch. I think the
wrong code issue might be the corruption of jump tables, but will need to get
past firewall to double check unless Martin beats me. It is his bug after all
;)

The problem as confirmed in Comment 9 no longer reproduce on mainline. So
problem is either fixed or went latent. I am going to try 4.6.

Confirmed on mainline. With "-flto -fprofile-use" libmozsqlite3.so no longer
segfaults. Must have been a recent change. It still segfaulted ~ a week ago.

Thanks for confirmation. My best bet is:
2011-05-29 Richard Guenther <rguenther@suse.de>
PR tree-optimization/49217
* ipa-pure-const.c (propagate_pure_const): Fix typos.
this bug could've caused symptoms seen here. Closing the PR then.
