#2257: validate hangs in configure
-----------------------+----------------------------------------------------
Reporter: nr | Owner:
Type: bug | Status: new
Priority: normal | Component: Build System
Version: 6.8.2 | Severity: major
Keywords: | Testcase:
Architecture: x86 | Os: Linux
-----------------------+----------------------------------------------------
Running ./validate on a freshly updated HEAD results in the script hanging
during the configuration process.
Here's what's on the screen:
{{{
checking whether float word order is big endian... no
checking for nlist in -lelf... no
checking leading underscore in symbol names... no
checking whether ld understands -x... yes
checking whether ld is GNU ld... yes
checking for .subsections_via_symbols... no
checking for GNU non-executable stack support... no
checking for clock_gettime in -lrt... yes
checking for clock_gettime... yes
checking for timer_create... yes
checking for timer_settime... yes
checking for a working timer_create(CLOCK_REALTIME)...
}}}
HEre's what 'top' has to say about what is running:
{{{
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
29457 nr 20 0 2000 480 368 R 88 0.0 9:18.12 conftest
}}}
And strace of that process reveals an endless stream of these:
{{{
--- SIGVTALRM (Virtual timer expired) @ 0 (0) ---
sigreturn() = ? (mask now [])
--- SIGVTALRM (Virtual timer expired) @ 0 (0) ---
sigreturn() = ? (mask now [])
--- SIGVTALRM (Virtual timer expired) @ 0 (0) ---
sigreturn() = ? (mask now [])
}}}
The system is a 32-bit Debian testing/unstable, uname -a says
{{{
Linux homedog 2.6.24-1-686 #1 SMP Sat Apr 19 00:37:55 UTC 2008 i686
GNU/Linux
}}}
The CPU is a dual-core AMD FX-60:
{{{
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 35
model name : AMD Athlon(tm) 64 FX-60 Dual Core Processor
stepping : 2
}}}
