Package: strace Version: 4.5.17+cvs080723-2 Severity: normal The following is from an attempt to strace Iceweasel on AMD64. It happens about 60% of the time that I launch strace, the other 40% of runs work correctly.
I am running "strace -p pid" to trace a running process. read(3, "\1\20b\200\22\5\0\0\0\0\0\0\0\0\0\0`\200\177\0\0\0\0\0\240\205\271\2\0\0\0\0\377"..., 4096) = 4096 read(3, "\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377\377"..., 1128) = 1128 read(3, 0x2451104, 4096) = -1 EAGAIN (Resource temporarily unavailable) *** glibc detected *** strace: malloc(): memory corruption (fast): 0x0000000001b1d610 *** ======= Backtrace: ========= /lib/libc.so.6[0x7feb319c1948] /lib/libc.so.6[0x7feb319c467f] /lib/libc.so.6(__libc_malloc+0x98)[0x7feb319c5a78] strace[0x408380] strace[0x4058de] strace[0x404616] /lib/libc.so.6(__libc_start_main+0xe6)[0x7feb3196c1a6] strace[0x401f69] ======= Memory map: ======== 00400000-00447000 r-xp 00000000 fd:01 196689 /usr/bin/strace 00647000-00648000 rw-p 00047000 fd:01 196689 /usr/bin/strace 00648000-00656000 rw-p 00648000 00:00 0 01b1d000-01b3e000 rw-p 01b1d000 00:00 0 [heap] 7feb2c000000-7feb2c021000 rw-p 7feb2c000000 00:00 0 7feb2c021000-7feb30000000 ---p 7feb2c021000 00:00 0 7feb31737000-7feb3174d000 r-xp 00000000 fd:01 575071 /lib/libgcc_s.so.1 7feb3174d000-7feb3194d000 ---p 00016000 fd:01 575071 /lib/libgcc_s.so.1 7feb3194d000-7feb3194e000 rw-p 00016000 fd:01 575071 /lib/libgcc_s.so.1 7feb3194e000-7feb31a98000 r-xp 00000000 fd:01 575285 /lib/libc-2.7.so 7feb31a98000-7feb31c97000 ---p 0014a000 fd:01 575285 /lib/libc-2.7.so 7feb31c97000-7feb31c9a000 r--p 00149000 fd:01 575285 /lib/libc-2.7.so 7feb31c9a000-7feb31c9c000 rw-p 0014c000 fd:01 575285 /lib/libc-2.7.so 7feb31c9c000-7feb31ca1000 rw-p 7feb31c9c000 00:00 0 7feb31ca1000-7feb31cbd000 r-xp 00000000 fd:01 575288 /lib/ld-2.7.so 7feb31ea1000-7feb31ea3000 rw-p 7feb31ea1000 00:00 0 7feb31eb9000-7feb31ebc000 rw-p 7feb31eb9000 00:00 0 7feb31ebc000-7feb31ebe000 rw-p 0001b000 fd:01 575288 /lib/ld-2.7.so 7fff39ea9000-7fff39ebe000 rw-p 7ffffffea000 00:00 0 [stack] 7fff39fff000-7fff3a000000 r-xp 7fff39fff000 00:00 0 [vdso] ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall] select(Aborted -- System Information: Debian Release: 5.0.3 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-2-amd64 (SMP w/2 CPU cores) Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/bash Versions of packages strace depends on: ii libc6 2.7-18 GNU C Library: Shared libraries strace recommends no packages. strace suggests no packages. -- debconf-show failed -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
