It will not gracefully recover from allocator/mutexes\\n * corruption etc., however, but at least \\\"most\\\" gentle crashes (null pointer\\n * dereferencing, integer division, stack overflow etc.) should be handled\\n * without too much troubles.\\n *\\n * The handler is thread-safe, but client must have exclusive control on the\\n * signal handlers (ie. the library is installing its own signal handlers on\\n * top of the existing ones).\\n *\\n * You must build all your libraries with `-funwind-tables', to get proper\\n * unwinding information on all binaries. On ARM, you may also use the\\n * `--no-merge-exidx-entries` linker switch, to solve certain issues with\\n * unwinding (the switch is possibly not needed anymore).\\n * On Android, this can be achieved by using this line in the Android.mk file\\n * in each library block:\\n *   LOCAL_CFLAGS := -funwind-tables -Wl,--no-merge-exidx-entries\\n *\\n * Example:\\n *\\n * COFFEE_TRY() {\\n *   call_some_native_function()\\n * } COFFEE_CATCH() {\\n *   const char*const message = coffeecatch_get_message();\\n *   jclass cls = (*env)->FindClass(env, \\\"java/lang/RuntimeException\\\");\\n *   (*env)->ThrowNew(env, cls, strdup(message));\\n * } COFFEE_END();\\n *\\n * Implementation notes:\\n *\\n * Currently the library is installing both alternate stack and signal\\n * handlers for known signals (SIGABRT, SIGILL, SIGTRAP, SIGBUS, SIGFPE,\\n * SIGSEGV, SIGSTKFLT), and is using sigsetjmp()/siglongjmp() to return to\\n * \\\"userland\\\" (compared to signal handler context). As a security, an alarm\\n * is started as soon as a fatal signal is detected (ie. not something the\\n * JVM will handle) to kill the process after a grace period. Be sure your\\n * program will exit quickly after the error is caught, or call alarm(0)\\n * to cancel the pending time-bomb.\\n * The signal handlers had to be written with caution, because the virtual\\n * machine might be using signals (including SEGV) to handle JIT compiler,\\n * and some clever optimizations (such as NullPointerException handling)\\n * We are using several signal-unsafe functions, namely:\\n * - siglongjmp() to return to userland\\n * - pthread_getspecific() to get thread-specific setup\\n *\\n * License:\\n *\\n * Copyright (c) 2013, Xavier Roche (http://www.httrack.com/)\\n * All rights reserved.\\n *\\n * Redistribution and use in source and binary forms, with or without\\n * modification, are permitted provided that the following conditions are met:\\n *\\n * 1.
