[Bug c++/42803] New: [(probably) regression gcc 4.4 on 32bit] c++ compilation hang

[l dot jirkovsky at gmail dot com]

Compilation hangs at the following file for several hours (then I stopped it).

According to http://www.rawtherapee.com/forum/viewtopic.php?t=1719 this seems
to be a regression in gcc 4.4 which is present on multiple GNU/Linux
distributions, all 32bit. 64bit doesn't seem to be affected.

Another discussion about this topic is hold in
http://aur.archlinux.org/packages.php?ID=11186

gcc 4.3 is said to work (I didn't tested it myself because compilation of gcc
takes several hours on my 32bit machine).
