--- Begin Message ---Package: php5-cli Version: 5.6.5+dfsg-1 Severity: normal Dear Maintainer, I've noticed some weird assembly being generated in the following piece of code. I've only noticed this in the Debian amd64 binary - DotDeb's version doesn't seem to have the issue. I suspect that this may be related to a compiler issue. >From main/streams/plain_wrapper.c: switch (value) { case PHP_STREAM_MMAP_SUPPORTED: return fd == -1 ? PHP_STREAM_OPTION_RETURN_ERR : PHP_STREAM_OPTION_RETURN_OK; case PHP_STREAM_MMAP_MAP_RANGE: do_fstat(data, 1); The above return statement (third line) seems to compile to the following: >x0x6a4740 <php_stdiop_set_option+672> cmp $0xffffffff,%r14d ; if (fd == -1) x0x6a4744 <php_stdiop_set_option+676> je 0x6a4632 <php_stdiop_set_option+402> ; return -1 x0x6a474a <php_stdiop_set_option+682> mov $0x1,%esi ; x0x6a474f <php_stdiop_set_option+687> mov %rbp,%rdi ; x0x6a4752 <php_stdiop_set_option+690> callq 0x6a4440 <do_fstat> ; do_fstat(%rdi, 1) x0x6a4757 <php_stdiop_set_option+695> xor %eax,%eax ; x0x6a4759 <php_stdiop_set_option+697> cmpq $0x400000,0x60(%rbp) ; %eax = -( *(%rbp+0x60) > 0x400000 ) x0x6a4761 <php_stdiop_set_option+705> setg %al ; x0x6a4764 <php_stdiop_set_option+708> neg %eax ; x0x6a4766 <php_stdiop_set_option+710> jmpq 0x6a4538 <php_stdiop_set_option+152> ; return %eax First bit looks okay, but I don't know what the rest is about. DotDeb's binary seems to compile to the following: >x0x693f55 <php_stdiop_set_option+437> cmp $0xffffffff,%r13d ; if (fd == -1) x0x693f59 <php_stdiop_set_option+441> je 0x693ea8 <php_stdiop_set_option+264> ; return -1 x0x693f5f <php_stdiop_set_option+447> xor %ebx,%ebx ; %ebx = 0 x0x693f61 <php_stdiop_set_option+449> jmpq 0x693de3 <php_stdiop_set_option+67> ; return %ebx ....which makes a whole lot more sense. I'm not sure what the "0x60(%rbp)" is referring to, but I've seen the comparison evaluate to true and false in various cases, sometimes causing mmap detection to fail. I've only tested this with PHP 5.6.5 so I don't know what version it showed up in. If you want a way to test it yourself, you can use the following PHP script: # cat >t.php <?php $fr=fopen('/bin/ls','rb'); $fw=fopen('/dev/null','wb'); stream_copy_to_stream($fr, $fw); ^D # gdb php break php_stdiop_set_option run t.php [ when it breaks, step through the assembly until you see the above ] -- Package-specific info: ==== Additional PHP 5 information ==== ++++ PHP 5 SAPI (php5query
