Ok, so you're using threads...
I have verified that:
- FreeBSD's pthreads implementation (libc_r) has a hard coded 1MB stack
for the "initial" thread (the one that starts all other threads), that
cannot be changed without rebuilding the library;
- the Linuxthreads port doesn't have the same limitation, and appears to
function sufficiently similarly to libc_r that the regression test
You should be able to try the linuxthreads build out by:
- install the linuxthreads port
- configure Python as normal
- modify the Makefile as follows:
+ remove any "-pthread" from the CC variable;
+ remove any "-lc_r" from the LIBS variable;
+ add "-I/usr/local/include/pthread/linuxthreads" to the CPPFLAGS
+ add "-L/usr/local/lib -llthread" to the LIBC variable.
- make test
I've just checked this recipe with a 2.2.3 build; it should also work with
a recent CVS sourcebase.
The sre recursion limits have been tweaked again in the current CVS tree
for FreeBSD, to reduce the risk of hitting the stack size limit.
