[Bug target/13145] New: [3.4 regression ] bootstrap failure on mips-linux

[debian-gcc at lists dot debian dot org]

bootstrap is broken on mips-linux between 20030815 and 20031030. I currently do
not have access to a mips machine to get this down to a specific date. 20031116
does show the same error (if this is of interest: on mipsel-linux, 20030909 did
bootstrap).

Confirmed, although in my case I'm seeing a segfault rather than
an out-of-memory error.  I think the problem is that stubs for
constant and pure functions are sometimes being called twice.
Working on a fix now.

The patch I just committed fixes bootstrap for me, but I'm not 100% sure
it's the same problem you were seeing.  Could you retest and open a new
bug report (or reopen this one) if you're still seeing problems?  Thanks.
