[Bug c++/22007] New: New testsuite failure on Tru64 UNIX V4.0F: g++.dg/eh/cleanup1.C

[gcc-bugzilla at gcc dot gnu dot org]

Between 20050113 and 20050609, there occured a new testsuite failure on the
4.0 branch on Tru64 UNIX V4.0F:

+FAIL: g++.dg/eh/cleanup1.C (test for excess errors)

FAIL: g++.dg/eh/cleanup1.C (test for excess errors)
Excess errors:
Stack overflow: pid 11784, proc cc1plus, addr 0x11fdfffe0, pc 0x12011b7ec
g++: Internal error: Segmentation fault (program cc1plus)

The default stack size on V4.0F is 2048 kB, compared to 8192 kB on V5.1B;
raising stack size to the latter value works.  Anyway, obviously stack
usage has increased considerably in this case.

Environment:
System: OSF1 rimsky V4.0 1229 alpha
Machine: alpha
	
host: alpha-dec-osf4.0f
build: alpha-dec-osf4.0f
target: alpha-dec-osf4.0f
configured with: /vol/gnu/src/gcc/gcc-4.0-branch-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --host alpha-dec-osf4.0f --build alpha-dec-osf4.0f --target alpha-dec-osf4.0f --with-gmp-dir=/vol/gnu/obj/gmp-4.1.3 --with-mpfr-dir=/vol/gnu/obj/gmp-4.1.3/mpfr --enable-languages=c,c++,f95,java,objc,ada

How-To-Repeat:
Bootstrap and test as described above.

A backtrace would be nice.

Sure: after running the test invocation with -save-temps, the failure is as
simple as

% ../cc1plus -fpreprocessed cleanup1.ii

The resulting stack trace ends in
