[Bug c++/19018] New: virtual memory exhausted

[david at starks-browning dot com]

The attached test-case causes cc1plus in gcc-3.3.4 to grow and grow until
memory resources are exhausted, on
SunOS 5.8 Generic_117350-05 sun4u sparc SUNW,Sun-Fire

This is essentially a re-statement of bug #16273, specifically for gcc-3.3.4.
It was originally reported against gcc-3.3.4, but then fixed for gcc-3.4.2,
not gcc-3.3.  I'm hoping it can be fixed in gcc-3.3 as well, but I don't
have the authority to re-open #16273.

Here is the invocation:

$ /usr/local/gcc-3.3.4/bin/g++ -v -c corba_original.included.cc

End of search list.

I will attach corba_original.ii which is derived from corba_original.cc
as attached to bug #16273 (as attachment id 6931), using --save-temps.
Unfortunately it is 40,000 lines long.

I'm interested because I see this on other code.  I don't have permission
to provide the other code, so I'm recycling this old test case rather than
supply a new one.

If someone wants to re-open #16273 and mark this as a duplicate, that would
be OK with me.

I can build & test snapshots but unfortunately I don't have cvs-pserver access.

Thanks for your help.

Sincerely,
David

Created an attachment (id=7750)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=7750&action=view)
Preprocessed test case.

Attachment as promised.  This is a pre-processed testcase derived from
"corba_original.cc" as attached to bug #16273, attachment id 6931,
using --save-temps.  I'm sorry it's 40K lines long, but it does reproduce
the problem for me on the above configuration.

I let GDR decide if he wants this patch to fix it for 3.3.x.

The same that fixed PR 16273. This bug is basically PR16273 which was marked as 
a 3.3 regression too but was closed as fixed after the patch was committed only 
to 3.4 and mainline.

True, but I don't believe the patch for PR16273 is applicable to gcc-3.3.
In fact, I am unable to reproduce the fault in gcc-3.3 using the 10,000-line
test case that was attached to PR16273.  Therefore, my guess is that the
smaller test case (attachment id 6664) was refined against gcc-3.4 and led to
the patch that fixed the symptom in gcc-3.4.  I don't know how much of that
effort could be applied to gcc-3.3.

Won't fix for 3.3.6. Suggest upgrade to 3.4.x
