encounter 'Broken pipe' error only while using step-by-step debug with GDB

There is unix-socket server written on PHP (but I don't think it has something to wit开发者_Python百科h it). Client side is written on c++ and based on boost::asio library. When I launch program normally - everything works fine, except one (not related to socket communication) bug that I obviously want to debug. But when I start step-by-step debugging it I immediately receive 'Broken Pipe' error on the steps which perform write operations on sockets. If breakpoint is set up after socket write operation - everything work fine until the next attempt to step over the write func.

Spent whole day trying to solve this problem, but unsuccessfully...

Had anyone met the same trouble?

• using GDB bundled with xCode 3.2.5 (64-bit) under OS X 10.6.7

GDB uses signals aggressively. If you want to install signal handlers, check out the following example:
