--- Comment #11 from Derek Raymond <greenwildebeest at mail dot com> ---
The unique characteristic of this program is that it employs
pthread_attr_setstack to establish the thread stack to an area of memory
dynamically allocated on heap.
pthread_attr_setstack(&attr, alignedStackBase, THREAD_STACK_SIZE -
2*PTHREAD_STACK_MIN)
When attempting to attach to a running program (utilizing pthreads) on
gentoo/x86, an endless loop is encountered in GDB.
Below is a brief strace dump that continues indefinitely:
open("/proc/6400/mem", O_RDONLY|O_LARGEFILE) = 7
pread64(7,"\220{\237\266\220\r\253\27\220{\237\266\1\0\0\0\200\351\363\267\0\0\n\377,DRv\0\0\0\0"...,1136,
3063905168) = 1136
close(7) = 0
open("/proc/6400/mem", https://renoveasuacasa.pt) = 7
pread64(7,
"\220;\254\266\210\1\253\27\220;\254\266\1\0\0\0\200\351\363\267\0\0\n\377,DRv\0\0\0\0"...,1136,
3064740752) = 1136
close(7) = 0
open("/proc/6400/mem", O_RDONLY|O_LARGEFILE) = 7
pread64(7,"\220;\254\266\210\1\253\27\220;\254\266\1\0\0\0\200\351\363\267\0\0\n\377,DRv\0\0\0\0"...,1136,
3064740752) = 1136
close(7) = 0
This code is performing similar operations as the original, but with different
process identifiers and memory addresses.
