[NTG-pdftex] update on "nasty pdf(la)tex bug on Solaris SPARC with ZFS"

I don't have a fix yet, just some more info: it's very likely that the problem is caused by inconsistent declaration of type longinteger. Tracing it down is not easy due to nested inclusion of header files, however a quick check can be done in gdb as follows: ,-------- | info type longinteger | | All types matching regular expression "longinteger": | | File pdftexini.c: | typedef long long int longinteger; | | File pdftex0.c: | typedef long long int longinteger; | | [...many files with the same declaration of longinteger...] | | File ../../../../src/texk/web2c/pdftexdir/writejbig2.c: | typedef long int longinteger; | | File ../../../../src/texk/web2c/pdftexdir/pdftoepdf.cc: | typedef long int longinteger; `-------- Note that the last 2 declarations are "long int" and not "long long int" longinteger is defined in web2c/config.h as off_t, which also has inconsistent declaration over different files: like longinteger, it's "long long int" for most files, except the following: ,-------- | File ../../../../src/libs/xpdf/goo/gfile.cc: | typedef long int off_t; | | File ../../../../src/texk/web2c/pdftexdir/pdftoepdf.cc: | typedef long int off_t; `-------- Thanh On Tue, Sep 09, 2008 at 04:20:58PM +0200, The Thanh Han wrote:

after some hours debugging, here is what I can confirm:

- the problem is with LFS enabled only; re-compiled pdftex with LFS disabled doesn't have this problem.

- the problem seems to be related to the value of variable pdfptr gone wild at certain moment, not to the *seek() functions.

- it seems a bug of pdftex, not compiler.

i tested the same on AIX, and got even weirder messages:

i'll recompile sparc-solaris and powerpc-aix using --disable-largefile and will look if it helps.

i didn't have an idea that LFS should be disabled because of such buggy behavior. the above messages on AIX look strange too. at least on solaris i get a meaningful error message.

Best, v.
