On Solaris 2.6, when the module 'tzset' is used, the function gettimeofday
is meant to be overridden by a function rpl_gettimeofday that invokes the
real gettimeofday.
Instead, the function gettimeofday is redefined in lib/gettimeofday.c,
and it recursively invokes itself. The Solaris cc turns this recursive
invocation into an endless loop:
! SUBROUTINE gettimeofday
!
! OFFSET SOURCE LINE LABEL INSTRUCTION
.global gettimeofday
gettimeofday:
/* 000000 104 */ st %o0,[%sp+68]
/* 0x0004 */ st %o1,[%sp+72]
! 105 !#undef gettimeofday
! 106 !#if HAVE_GETTIMEOFDAY
! 107 !# if GETTIMEOFDAY_CLOBBERS_LOCALTIME
! 108 ! /* Save and restore the contents of the buffer used
for localtime's
! 109 ! result around the call to gettimeofday. */
! 110 ! struct tm save = *localtime_buffer_addr;
! 111 !# endif
! 113 ! int result = gettimeofday (tv, (struct timezone *) tz);
.L77000014:
/* 0x0008 113 */ ba .L77000014
/* 0x000c */ nop
/* 0x0010 0 */ .type gettimeofday,2
/* 0x0010 0 */ .size gettimeofday,(.-gettimeofday)
This fixes it. The bug was introduced on 2010-02-23, while fixing the behaviour
of this module on mingw.
