Question on signals with Linux

["Mark Rivers" <rivers@cars.uchicago.edu>]

Folks,
 
I am trying to write a driver for the Prosilica Gigabit Ethernet cameras under Linux.  They provide a pre-built library for controlling their cameras.  One of the notes for this library says the following:
 
* As the API use some signals internally, it is required to "protect" some of your system calls (such as sem_wait)  from been interupted. This can be done by calling the system call from within a loop and only exiting from it if there was no error or if errno is different from EINTR.
 
When I run an EPICS application that calls this library it crashes and this is the output of gdb:
 
(gdb) bt
#0  0x0808ce33 in SIGAction ()
#1  0x0821bf4d in ignoreSigAlarm (signal=14) at ../../../src/libCom/osi/os/posix/osdSignal.cpp:109
#2  <signal handler called>
#3  0x00110416 in __kernel_vsyscall ()
#4  0x002ce671 in select () from /lib/libc.so.6
#5  0x0808d21e in pPvMultiplexer::Body ()
#6  0x08090e00 in _ThreadFunction ()
#7  0x003b932f in start_thread () from /lib/libpthread.so.0
#8  0x002d620e in clone () from /lib/libc.so.6

The same application works fine under Windows, linked with a Prosilica DLL that uses the identical API to their Linux library.
 
Does anyone have ideas on how to fix this?
 
Thanks,
Mark
