--- Begin Message ---Package: libc6 Version: 2.19-18 Severity: normal Tags: upstream Dear Maintainer, On a ppc64le host, programs compiled with -pg fail to record profiling information at run-time. At start-up time, the compiled program prints monstartup: out of memory and does not produce a gmon.out file. A complete repro case is included below. I believe the problem is in the Glibc 2.19 sources, file sysdeps/powerpc/powerpc64/entry.h. The definition of TEXT_START is appropriate for ppc64, i.e. version 1 of the ELF PPC64 ABI, where function pointers have one level of indirection before reaching the function code. Version 2 of the ELF PPC64 ABI, as used in ppc64le, does not have this indirection. Hence the address of the _start symbol should not be dereferenced. Repro: $ cat tst.c int main() { return 0; } $ gcc -pg tst.c $ ./a.out monstartup: out of memory $ gdb a.out [...] (gdb) b __monstartup Breakpoint 1 at 0x100008d4 (gdb) run [...] Breakpoint 1, 0x00003fffb7ed2d78 in __monstartup (lowpc=4053955894390558722, highpc=268437728) at gmon.c:104 Note the obviously wrong value of the lowpc parameter passed to __monstartup by __gmon_start__ -- System Information: Debian Release: 8.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: ppc64el (ppc64le) Kernel: Linux 3.16.0-4-powerpc64le (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=locale: Cannot set LC_ALL to default locale: No such file or directory UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libc6 depends on: ii libgcc1 1:4.9.2-10 libc6 recommends no packages.
