 // We want to break into the debugger in Debug mode, and cause a crash dump in
 // Release mode. Breakpad behaves as follows:
 //
 // +-------+-----------------+-----------------+
 // | OS    | Dump on SIGTRAP | Dump on SIGABRT |
 // +-------+-----------------+-----------------+
 // | Linux |       N         |        Y        |
 // | Mac   |       Y         |        N        |
 // +-------+-----------------+-----------------+
 //
 // Thus we do the following:
 // Linux: Debug mode, send SIGTRAP; Release mode, send SIGABRT.
 // Mac: Always send SIGTRAP.
