regress failed

[aperi2007]

Hi,

during the check phase of compile the last version of postgis trunk I see three errors: regress, lwgeom-regres and ticket.

regress failures on windows mingw

Actually I get a lot of errors too running 9.0.0 windows (mingw 32-bit) with gserialized on. Don't recall getting this many before (aside from the one's Paul said would fail)

regression failures on GNU/Linux 32bit

[strk]

failures on GNU/Linux 64bit (r6521)

[pramsey]

Fixed at r6523

[strk]

Fixed on the 64bit, still 2 failing on the 32bit (measures and tickets) Both tested as of r6526

tickets and measures regressions on 32bit GNU/Linux r6526

[nicklas]

Yes, strk, I did get stuck with the measures failure we discussed in #703 with 80 bit vs 64 bit, inside calculations vs variables.

I cannot understand why it doesn't get truncated to 64bit when I store it in a variable and then uses it from there.

And why can 64 bit Linux and windows handle this but not 32 bit Linux?

Before we just camouflage this behind some rounding I would like to ask: Is there anything special about this precision error. Isn't it likely that we have this issue in many places? Should I dig deeper in this to solve it, or is it just another precision problem.

And why can 64 bit Linux and windows handle this but not 32 bit Linux?

I don't know the code, but perhaps could be a variable not empty before ?

I know some difference there is between windows and unix. many compilers don't empty variable on their definition.

[nicklas]

measures should be fixed in r6543

aperi2007, I don't think that is the problem because I initialised a variable only to do that single thing (no reuse of the variable) and it gives the tiny error about 1e-15 at first run.

Andrea,

Are you still experiencing regression failure issues? I think everyone else is set.

[aperi2007]

Hi robe.

The failure is fixed .

Close you this ticket ?
