[Bug c/15981] New: internal compiler error: in insert_aux, at tree-ssa-pre.c:1363

[v dot haisman at sh dot cvut dot cz]

I get this internal compiler error on one of the Perl 5.8.4 source files
(preprocessed file is attached) with -O2 and -O3. With -O1 option it passes.


logout ~/tmp/perl-5.8.4/ext/File/Glob>gcc -save-temps -c   -DHAS_FPSETMASK
-DHAS_FLOATINGPOINT_H -fno-strict-aliasing -I/usr/local/include
-I/home/4/wilx/include -O2 -march=pentium3   -DVERSION=\"1.02\"
-DXS_VERSION=\"1.02\" -shared "-I../../.."   bsd_glob.c
bsd_glob.c: In function `glob0':
bsd_glob.c:610: internal compiler error: in insert_aux, at tree-ssa-pre.c:1363
Please submit a full bug report,
with preprocessed source if appropriate.
