[JoesCat]

Hi Arturo,
Thank you for the printout of where it was failing. I looked at
https://buildd.debian.org/status/logs.php?arch=mips&pkg=libspiro&ver=1%3A0.3.20150131-2
and I did not know where it could be failing.

Looking at your log files, libspiro (mips) is failing at creating pthreads.

Multi-thread testing of libspiro.
bad pthread_create[167]
time 0.747777

At the time I created 20150131, I put an arbitrary number of expecting 300 
pthreads to be run in parallel, but the mips only managed to make 167 
before running out of space.
I've created a fix already for this (I think) in file tests/call-test.c at 
approximately line 423 if you look here:
https://github.com/fontforge/libspiro/commit/567c19430614c4f485ea3c4873b343170b2ca469
"Sawtooth through the test data to complete all S_TESTS using pthreads"

This fix will allow computers with less memory, or allowance for less
pthreads to continue sawtoothing through the pile of data.
I also increased the number of tests from 300 to 3000 to match the number
of tests done by computers lacking pthreads (equal number of tests).

I am a little concerned if the increase of tests from 300 to 3000 may be an
issue since the various FPU may put out slightly different values which may
be an issue with data[2] when doing the 3000 (3x1000) tests.

Can you please test HEAD
https://github.com/fontforge/libspiro
If HEAD is working, I would like to make this the next release (preferably
after finding-out what exactly failed with the other architectures too).
http://buildd.debian-ports.org/status/package.php?p=libspiro&suite=sid
(I did not see resulting log files for the failed units here).

Thank you for providing a mips log file to see where the problem appeared.
Joe

Hi Arturo,
I recall when working with Borrero Gonzalez wrote:

My first reaction is that there is a mis-match of "{" to "}" between the
start of the function spiro_iter at 687 down to line 812. To be on the safe
side, you may want to copy file spiro.c into your mipsel machine again, just
to ensure there was no file corruption.

My second thought is how another user had trouble with an older compiler
when there was a mixture of commands in the initialization (the older
compiler I tried, did not appear to have these issues). So I'm thinking
that I need to also fix this at line 688 from:
int cyclic = s[0].ty != '{' && s[0].ty != 'v';
int i, j, jj;
double norm;
int n_invert;

to:
int cyclic;
int i, j, jj;
double norm;
int n_invert;

cyclic = s[0].ty != '{' && s[0].ty != 'v';

My third thought is the -D_FORTIFY_SOURCE=2 having trouble with the memcpy
statements. More reading here:
https://gcc.gnu.org/ml/gcc-patches/2004-09/msg02055.html

I have moved many of the initializations outside of the "if" statements and
put them at the top of the function. This may help ease any complications
of initialized values mid function, particularly of the complex type such
as derivs[4][2][4]

The bug is not reproducible, so it is likely a hardware or OS problem.

This suggests to me a possible shortage of memory while gcc was
preprocessing spiro.c during checks for -D_FORTIFY_SOURCE=2

Ensure you have plenty of swap space if you don't have much memory.
If your computer ran particularly slow and accessed the harddrive
frequently, you may want to check that you didn't reach 100% memory use, or
try avoid running big programs at this time.

I've loaded another update with fewer variable inits mid-function into
HEAD, hopefully this cures the problem if you saw it more than once
earlier.

I'm not sure about your reply, is this issue considered fixed? or is there still a problem?
If problem, do you have a new log?

Sorry, I didn't manage to get time to give additional testing. Please, give
me a couple more of days.

[JoesCat]

Okay, Thanks Arturo. I wasn't sure if this was done due to the wording of your reply. I'm very interested to know the results since this is a non-x86 CPU and FPU with RISC behaviour and another method of floating point processing which may give matching results, or maybe deviate a bit and fail in one of the 3000 pthread tests.

[aborrero]

I was able to build libspiro on mipsel :-)

The test suite ends like this:
