1 Hi all,
2
3 I just had a crash from the CLI version of PHP that I wanted to
4 debug, so I enabled core files, triggered the crash, and tried to
5 load the core file into GDB:
6
7 arcadia ~ # gdb /usr/lib/php5/bin/php core
8 GNU gdb 6.3

15 There is absolutely no warranty for GDB. Type "show warranty" for
16 details.
17 This GDB was configured as "i686-pc-linux-gnu"...(no debugging
18 symbols found)
19 Using host libthread_db library "/lib/tls/libthread_db.so.1".
20
21 "/home/bootc/core" is not a core dump: File format not recognized
22 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
23 (gdb)

26 Yet, file clearly states this is a core file, which I fully expect it
27 to be:
28
29 arcadia ~ # file core
30 core: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-
31 style, SVR4-style, from 'php'
32
33 What the heck is happening?
