[Bug lto/43786] New: lto crash and/or infinite loop

2010-04-18 Thread baronchaos at ymail dot com 
- was trying to compile bc on gentoo
- lto1 process didnt finish after over an hour

- i cat as many c-files as possible into my.c and used resulting my.i

- different flags result in different reaction.

a)
x86_64-pc-linux-gnu-gcc -c -o my.o my.i -flto 
x86_64-pc-linux-gnu-gcc -c -o numeric.o numeric.i -flto -fshort-double
x86_64-pc-linux-gnu-gcc -o dc my.o numeric.o -flto

lto1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See http://bugs.gentoo.org/ for instructions.
lto-wrapper:
/usr/x86_64-pc-linux-gnu/gcc-bin/4.5.1-pre/x86_64-pc-linux-gnu-gcc returned
1 exit status
collect2: lto-wrapper returned 1 exit status


b)
x86_64-pc-linux-gnu-gcc -c -o my.o my.i -flto
x86_64-pc-linux-gnu-gcc -c -o numeric.o numeric.i -flto -O1
x86_64-pc-linux-gnu-gcc -o dc my.o numeric.o -flto -finline-small-functions

... infinite loop (or taking hours)


- x86_64-pc-linux-gnu-gcc -v
