dump issue with one conformance file: file9.jp2 #96

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. j2k_dump -i file9.jp2 -o dump-file9.jp2-1.txt
2. j2k_dump -i file9.jp2 -o dump-file9.jp2-2.txt
3. compare the output files

Dump is correctly done but output is variable. More precisely stepsize values 
are different.

valgrind is going nuts on this file:

Breakpoint 3, j2k_read_siz (j2k=0x418300) at 
/home/mathieu/Projects/OpenJPEG/svn/branches/openjpeg-1.5/libopenjpeg/j2k.c:602
602     j2k->default_tcp->tccps = (opj_tccp_t*) opj_calloc(image->numcomps, 
sizeof(opj_tccp_t));
(gdb) p image->numcomps
$3 = 1

and then:

Breakpoint 4, j2k_dump_cp (fd=0x418010, img=0x41a730, cp=0x419970) at 
/home/mathieu/Projects/OpenJPEG/svn/branches/openjpeg-1.5/applications/codec/j2k
_dump.c:642
642             fprintf(fd, "      csty=%x\n", tccp->csty);

(gdb) p img->numcomps
$4 = 3

CQFD

I can no longer reproduce this behavior, this has been fixed since then. 
closing.
