[Bug tree-optimization/32891] New: [4.2 Regression] PRE goes crazy on YQPkgTechnicalDetailsView.cpp

[rguenth at gcc dot gnu dot org]

In 4.2 with -O2 we use 1.5GB compiling the testcase while with 4.1 we only
needed
360MB.  Using -fno-tree-pre fixes the memory regression.

Some recent 4.3 ICEs for me on the testcase (you need -O2 -fpermissive) with

/usr/include/boost/regex/v4/basic_regex_creator.hpp:515: internal compiler
error: in expand_or_defer_fn, at cp/semantics.c:3220
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

so I have no way to verify if the problem persists in 4.3 at the moment.

Preprocessed source please.
I don't make installed versions of the compiler to play with :)

preprocessed testcase (trunk)

Note preprocessed source is incompatible wrt different gcc versions and so
useless
for a comparison.  But especially for you - here's  preprocessed source for
trunk.

Change target milestone to 4.2.3, as 4.2.2 has been released.

This will not be fixed on the 4.2 branch.  Closing as fixed for 4.3.0.
