problems with dejagnu

- Subject: problems with dejagnu
I'm getting different results every time I run `make -k check'.
Is this normal? ;-)
As far as I can tell, the intermittent additional failures that I get
are spurious ones which seem to be caused by the output of gcc being
somehow truncated. The tests work fine if I execute run them manually
using ".../xgcc -B.../ ...". The tests which are giving intermittent
results are gcc.dg/typespec-1.c and gcc.dg/format/ext-3.c,
both of which have a large number of errors or warnings, and the symptom
is that according to runtests, gcc is not reporting the last few.
My environment is as follows:
- OS is Debian Linux 3.0 (stable)
- CPU is x86
- dejagnu version 1.4.2-1.1
- expect version 5.32.2-4
- tcl version 8.3.3-7
- binutils version 2.12.90.0.1-4
- gcc sources version gcc_ss_20020909
(obtained by `cvs checkout -rgcc_latest_snapshot gcc')
Here's an example of the kind of failures I'm getting:
FAIL: gcc.dg/typespec-1.c unsigned long long int double (test for errors, line 934)
FAIL: gcc.dg/typespec-1.c unsigned long long int signed (test for errors, line 935)
FAIL: gcc.dg/typespec-1.c unsigned long long int unsigned (test for errors, line 936)
FAIL: gcc.dg/typespec-1.c unsigned long long int _Bool (test for errors, line 937)
FAIL: gcc.dg/typespec-1.c (test for excess errors)
FAIL: gcc.dg/format/ext-3.c bad %-0 (test for warnings, line 212)
FAIL: gcc.dg/format/ext-3.c bad %_0 (test for warnings, line 213)
FAIL: gcc.dg/format/ext-3.c bad %^# (test for warnings, line 215)
FAIL: gcc.dg/format/ext-3.c (test for excess errors)
Any hints on how to fix or work-around this problem would be much appreciated.
P.S. I'm also getting failures for the following four tests, but these
seem to be failing reliably ;-)
FAIL: gcc.dg/cpp/c++98-pedantic.C (test for warnings, line 9)
FAIL: gcc.dg/cpp/c++98-pedantic.C (test for excess errors)
FAIL: gcc.dg/cpp/c++98.C (test for excess errors)
FAIL: gcc.dg/noncompile/incomplete-1.c (test for excess errors)
