From a7a0c7a1bf3461bd43aacaf03ee5015903ead168 Mon Sep 17 00:00:00 2001 From: Wladimir J. van der Laan Date: Sat, 14 Apr 2012 09:41:05 +0200 Subject: [PATCH 1/1] Show a message box when runaway exception happens This is more clear to users than when the program simply disappears (usually during initialization). It still logs the message to the console and debug log as well. --- src/qt/bitcoin.cpp | 13 +++++++++++-- 1 files changed, 11 insertions(+), 2 deletions(-) diff --git a/src/qt/bitcoin.cpp b/src/qt/bitcoin.cpp index bfb49cb..463b2cf 100644 --- a/src/qt/bitcoin.cpp +++ b/src/qt/bitcoin.cpp @@ -119,6 +119,15 @@ std::string _(const char* psz) return QCoreApplication::translate("bitcoin-core", psz).toStdString(); } +/* Handle runaway exceptions.
