How did you arrive at 70 doubles and 43 doubles length values? the 70 is the final offset 432 + 16 + 96 == 544 plus 16 for the alignment divided by 8 (size of double). I checked this also with the debugger. The 43 is the final offset 232 + 8 + 96 == 336 plus 8 for the alignment divided by 8. > 2. It appears that __SPE__ is not accounted for in setjmp.h The SPE is only used in 32-bit processors without a FPU or Altivec unit. So, 256 bytes for the jmp_buf are enough. -- embedded brains GmbH Herr Sebastian HUBER Dornierstr. 4 82178 Puchheim Germany email: [email protected] phone: +49-89-18 94 741 - 16 fax: +49-89-18 94 741 - 08 Registergericht: Amtsgericht München Registernummer: HRB 157899 Vertretungsberechtigte Geschäftsführer: Peter Rasmussen, Thomas Dörfler Unsere Datenschutzerklärung finden Sie hier: https://embedded-brains.de/datenschutzerklaerung/
