741104 - internal compiler error: in tree_nrv, at tree-nrv.c:143

Status: NEW

(Firefox Build System :: General, defect)

Description

[Ben Bucksch (:BenB)]

Environment:
- Ubuntu 10.04 64bit
- g++-4.4.real (Ubuntu 4.4.3-4ubuntu5.1) 4.4.3

The last compile a while a go on the same system worked fine, so this is a regression.

Does it fail with 4.4.7? 4.5?  I think we've had some fun errors with 4.4 in the past.

Comment 3

[Ben Bucksch (:BenB)]

I can't easily install another compiler, I didn't find newer official packages.

Comment 4

[Ben Bucksch (:BenB)]

(But I assume newer versions are fine, given that the tree isn't burning, and given the above gcc bug report.)

Comment 5

[Kyle Huey (Exited; not receiving bugmail, old account, do not use)]

Well the GCC bug you linked is fixed in 4.4.2 if I read it correctly, and you're using 4.4.3.

Tinderbox is using 4.5.x IIRC.

Thanks! Confirmed, attachment 606580 [details] [diff] [review] fixes this bug here for me.

(Not marking DUP, but dependent, because the summary of the other bug is about something else.)
