What 134 Means
The 134 error on the Linux system errors indicates self-abort — the process called abort() after detecting a state it cannot recover from. This typically occurs due to a failed assert() or static assertion in c/c++ code invoking abort by design.
Exit code 134 is the arithmetic of 128 + 6, and the sender is the process itself: SIGABRT fires when abort() runs after an internal check declares the state unrecoverable.

Capture the abort message
The reason for the abort is printed to standard error just before death; keeping the last lines preserves it.
./your_program 2>&1 | tail -n 40Replay with memory checking
Valgrind instruments every allocation and reports the invalid free or write that pushed the heap into an abort-worthy state.
valgrind --error-exitcode=1 ./your_programCross-check the kernel's view
The kernel log confirms the abort and rules out an external signal sender.
dmesg -T | tail -n 20
Technical Background
Exit code 134 means the process ended itself on purpose. abort() is the standard library's confession mechanism: an assert failed, the heap manager found impossible metadata, or an exception crossed a boundary marked noexcept — each is a state the code has declared unrecoverable, and the correct move under the language's rules is a loud stop.
The loudness is the feature. Unlike a segfault, which dies where it stands, an abort path normally prints the reason first: the exact assert expression, or a glibc sentence naming the corrupt chunk. That message on stderr is the entire diagnosis in most cases.
Because the trigger is internal state rather than a bad pointer dereference, heap corruption often surfaces as 134 before it ever reaches 139 — the allocator's consistency checks fire earlier than the first wild access would.
Common Causes
- A failed assert() or static assertion in C/C++ code invoking abort by design
- glibc heap-integrity checks detecting double frees or corrupted allocator metadata
- A C++ exception escaping a noexcept function and reaching std::terminate's abort
Typical Scenarios
- A unit-test binary failing an assert and aborting with the failed condition printed above the exit
- A long-running C++ service printing a glibc message such as 'double free or corruption' before dying
- An exception thrown through a noexcept boundary terminating the process via std::terminate
What to Know
The abort message on standard error names the failing check directly. When the cause is heap corruption rather than a plain assert, a memory-error tool replaying the run tends to expose the allocation that poisoned the state.
Frequently Asked Questions
Common questions about Linux 134 error
134 (SIGABRT) is self-inflicted — the program's own checks called abort(). 139 (SIGSEGV) is kernel-inflicted after an invalid memory access. An abort arrives with a diagnostic message on stderr; a segfault usually dies silently.
On the process's own stderr. Assert failures name the file, line, and expression; glibc names the heap check that tripped. Capturing standard error is what makes a 134 diagnosable.
The signal can be caught, but abort() keeps its final word — after the handler runs, the process still terminates. Treating a caught SIGABRT as survivable is a misreading of the mechanism.
